Password Value sometimes missing, Text sometimes incorrect

[mkromberg]

Run DemoPassword.

1. If you immediately click "OK", the application will crash because no value is returned for the Value property.
2. If you enter something in the password field, delete it, and then hit OK, the password is reported as "2":

{"WG":{"ID":"F1.∆pP1.B31001","Properties":["Text","Value"],"WGID":"6"}}
{"WG":{"ID":"F1.∆pP1.B31001","Properties":{"Text":"2","Value":""},"WGID":"6"}}
Password Text: "2"
Password Value: ""
