Hi Sebastiaan,

Since upgrading to 0.26 on Ubuntu 12.04 (Python 2.7.3), OpenSesame closes without warning when scrolling through the Preferences pane.

Steps to reproduce: run OpenSesame, select Tools -> Preferences, use the mouse to scroll to the bottom of the preferences window. I have not been able to reproduce this bug when using the keyboard.

Other notes: Running opensesame --debug gives the following error:

Fatal Python error: (pygame parachute) Segmentation Fault
Aborted (core dumped)

Let me know if I can provide any other information that might help, and thanks in advance!

Hi Dave,

Thank you for reporting this bug. I think what causes the crash is the box labelled "Interface style". If you scroll through the preferences, at some point your mouse will hover over this box and the scrolling will change the interface style. There is a bug in Qt4 (the graphical toolkit) which causes a crash when you try to change the interface style while the programming is running, at least sometimes.

Could that be it?

In 0.27 (under development) I fixed this by having the interface style take effect only when OpenSesame loads.

Please keep me informed if you experience any more of these crashes!

Cheers, Sebastiaan

Hi Sebastiaan,

Yes, that seems to be it! When I try to change the Interface Style by selecting it, OpenSesame closes and I receive the same debug message. Similarly, if I move the mouse off to the side (so it doesn't hover over that box) I can scroll through the Preferences pane with no problems.

Marking this as solved. Thanks for your help!

Best, Dave
