Systray icon no displayed under windows seven

I make an application that run permanently that why I use a systray icon, but it's not displayed under windows seven. It's works fine on XP. I am using the .ico file that have a 32x32 resolution.

Hi!

I'm using the QSystemTrayIcon with a QIcon, that loads its data from a resource. Works like a charm in Win7 and XP.

Try to help yourself and build a minimal application, that just loads a systemtray icon.

Good luck,

Johannes

I have made some tests. It works on only one PC that is really really strange, I have remove project and checkout it completely again to be sure there is no more files than on other PCs.
I also have made a minimal application that just works fine, but there is no difference with my project.

I am using visual studio 2010 with Qt Addins plugin 1.1.7 and Qt 4.7.1.
Not my qrc file is correctly loaded. I have put a break point in the generated file to check it.

Code:

	if (argc > 0)
	{
		QFileInfo	info;
 
		info.setFile(argv[0]);
		QDir::setCurrent(info.canonicalPath());
	}
 
	QApplication		application(argc, argv);
