Problem with display Blender 2.48 RC1


I don’t know, if this is the right thread for my question, so please admins: Feel free to move this one to the right place.

Since two days i’m trying to get the first release candidate from Blender to work, but unfortunately there seems to by no way at the moment. Everytime i try to start blender, it loads at the first glance correct, and there are no errors an the console.
But when the splash screen has loaded, at doesn’t disappear and reveals the GUI as usual. It keeps standing above an empty blender-main-window.
Only if the mouse-cursor is moving above the several elements from the GUI, this elements are showing up -piece by piece.:frowning:

Until the laste release 2.47, blender was working correct on my machine. I’m running WinXP Pro, Python 2.5.2, Graphics: Nvidia GeForce 7900.

Maybe someone has an idea, where i can get some hints for a solution?

Thank a lot, and sorry for my bad english,
