Care to elaborate?

the particle lifespan set button locked up my glut window hard... might not be sufficiently skeptical of input?

some more elaboration might be helpful. Such as, did you enter a larger number for the min than the max? I admit this was done quickly and I didn't check to make sure the user entered proper data.

Also, it is a plain text field which means it accepts chars (also a potential hazard). I only picked up QT a couple days ago. Maybe @franckamayou , @jtfallon , or @ltran1 know how to limit the input to floats only.
