Some dialogs are broken on my system.
- some file selection dialogs (open and save). Not all of them though. File selection dialogs in some Qt apps (including Qt demo) don't work anymore (when using native dialogs) and file selection dialogs in Visual Studio 2010 do not work anymore. (They do work in visual studio 2008).
- most of the dialogs in Visual Studio 2010, such as add reference, or icon dialog, but not the preferences dialog.
I have tried to find the problem in other applications, with no luck. File dialogs work fine in for example MS Paint and Office 2007. Some applications use "old" file selection dialogs (with Windows 98 style buttons), and those work too. Some software that uses Qt does have working file selection dialogs.
Edit: when the dialog should show up, the main window loses focus (just like it would when a dialog does show up), but then regains focus after about 0.1 second.
Perhaps this is a problem with a specific window flag?
I would appreciate anything that can help me solve this problem, as Visual Studio is virtually unusable now.
OS: Windows 7 Home Premium 64-bit.
