Stability improvements for 5.23

[gileli121]

Over the past few months, I have intermittently received various reports of fatal errors from the global exception handler window.

I have identified six types of fatal errors. I will begin addressing them in order of frequency, starting with the most common and working down to the least common.

I will update this ticket with comments on the status of each error fix.

Error 3 (10 users reported) [Fixed 6-Oct-2024]

Comment:
Not sure what happened.
I noticed WindowTop was not appearing on my windows, so tried to re-launch it.
My explorer crashed yesterday, so WindowTop may have still been running, but no longer active on my windows due to explorer.exe crashing yesterday.

Error 3 status update

Unable to reproduce error 3. "Fixed" by ignoring the error.
According to my investigation, this error can occur in the MS Store version during an update check. I have identified the failing code but have been unable to reproduce the error. The logs indicate that the error does not always occur to the end user. I have wrapped the problematic section with a try-catch block and added additional logging. Since the error is not critical and does not always happen, and the app will retry the update check later.

Error 1 status update

This error, while still rare, can occur when using multiple monitors. It is more likely to happen when switching or disconnecting monitors while numerous windows are open, particularly if they have SET-TOP enabled.

I have updated the code, and this issue should now be resolved.

Error 2 status update

This error is somewhat similar to Error 1, as it also relates to monitors. However, I was unable to reproduce it. It may be resolved now, and I hope it won't be reported again.

Error #372

I tried to reproduce the issue on a Swedish VM without success. It worked as expected: on the first run, the app detected the OS language and displayed in Swedish.

Additionally, when switching the language from English to Swedish, the change takes effect immediately without the need to restart WindowTop

Fixed Issue #376

I’ve released a new version, 5.23.4, which includes the latest fixes. It is currently marked as a pre-release; once it proves stable, it will be designated as a regular release.

Download:

• Installer Version
• Portable Version

Full Release Notes:

• Enhanced stability by addressing two common crash errors (errors 1 and 3 from #383).
• Resolved the "Failed to disable transparency for the window" issue that occurred when closing the window with Glass mode enabled (#376).

Please let me know how it works for you!

Error 4 Status Update

This error occurs in very rare situations, likely due to a race condition (multi-threading issue). It can happen when a user drags the toolbar arrow () while the window is closing or has been dereferenced—potentially due to moving to another virtual desktop or a similar action. In these cases, one thread attempts to access a reference (the window variable) that another thread has set to null, leading to a null reference exception.

Since this scenario is extremely rare, it is handled with a catch (NullReferenceException ex) block, which also logs all null variables involved in the relevant code. While it’s likely only the window variable will be null, I log other variables as a precaution.

This is not a new issue; I have encountered it before in another part of the toolbar arrow UI, where the same workaround was implemented and proved effective. Although catching exceptions can be CPU-intensive, in this case, it occurs in code that does not execute frequently. Most of the time, it only runs while the user is dragging the arrow, so the performance impact is minimal.

Error 5 Status Update

I attempted to reproduce the issue but was unable to do so.

After reviewing the logs, I found that the error is related to a failure in accessing the cache.json file for writing. Upon closer inspection, I discovered something unusual:

The app is trying to access the file at the following path:
C:\program Files\WindowTop

This is unexpected because the app is supposed to be installed in the standard path:
C:\Program Files\WindowTop

The folder where most applications (except Microsoft Store apps) are installed is named "Program Files", not "program Files" with lowercase letters.

Possible Causes

After considering the situation, I identified three likely explanations for this issue:

1. Anti-virus/Malware Interference

The app might be running in a sandboxed environment due to interference from anti-virus or anti-malware software.
Some security tools can alter or redirect application paths during execution, causing this behavior.

2. Manual Folder Renaming

It’s possible that the "Program Files" folder was accidentally renamed to "program Files".
This could also explain any system instability, such as Explorer crashes, as "Program Files" is a critical OS directory.

3. Unconventional Installation Method

The installer we provide does not allow users to select a different installation path. However, if the app was installed using an unofficial or third-party installer, it might have resulted in an incorrect installation location, such as "C:\program Files" instead of "C:\Program Files".

Next Steps

I asked the user to verify that none of these scenarios apply to their setup.
