Every Qt app in WinXP - 'blocked' input?

aabbaa

Hello.

I have Windows XP Pro SP3, and Geforce 2 MX 200/400.

I installed SMPlayer, which is Qt app and after run weird things happen:

there are no hover(mouse over) on every buttons (in toolbar) or sometimes hover shows up,
often when I click any button (on toolbar) then nothing happens,
often application looks like to be 'suspended'.

That things happens only to Qt apps, other apps works OK.
Is it a virus/malware or sth?
Maybe graphic card is wrong for Qt?

Sorry for my English.

Does this also happen in your own programs, or what exactly is the question?

If you're not a C++/Qt-Programmer but just a user of Qt programs, this question is better placed in the forum/mailing-list of the respective application, or maybe KDE.

This happens in my own programs but also to others programs based on Qt (like SMPlayer). The problem occurs only on one computer (on others ~100 client computers Qt like apps works OK). In what could be the problem?

Maybe some .DLL with problem....
Do you try to reinstall the QtCreator?

This is client machine without QtCreator, Qt SDK or system Qt libraries.

Can you check the executable using the Dependency Walker?
Maybe can show you something...

I'm not sure but I don't think that can be the Video Graphics or GPU Driver...

Did you check a CPU usage when you start the qt application?!
