Clipboard hangs up other applications

[alain coste]

Hello
I am a QtNewbie, and I have a problem with the use of the clipboard.
If I execute the following code :

QApplication applic(argc,argv);
QClipboard *clipboard = QApplication::clipboard();
clipboard->setText("blablabla");

Any application which tries to paste the content of the clipboard hangs up, and wakes up only if I kill the QApplication applic.
It seems Qt doesn't release the clipboard after setting text. I couldn't find any method to do this. What am I missing ?

By cons, if I copy to the clipboard without Qt (via OpenClipboard ... SetClipboardData ... CloseClipboard) everything works fine.

My OS is Windows XP (sorry...).
