In the preview? The preview is the little shrinked preview of a screensaver in the systems screensaver dialog, right? Well there you won't see anything with this screensaver.
Yes, I already added a mutex function, as I described in my last post (findwindow thing) and it works well so far.
I have also solved the problem with the black flashing small windows.
A new version is uploaded, you may try this one again, thanks.
EDIT: just found another bug, in the installer this time:
When the user selects an other sceensaver then this one will vanish from the list of screensavers in the OS's dialog.
Solution: Never choose an other screensaver :P
