The Install on my msi wind u100 was great. All drivers are working. ;-) nice

My problem:
Pictures,i mean the file names, are demaged in the way that the have mistakes in it by viewing. The Coverflow have for example mistakes.
Pixel error in picture for example or a grey bottom line her view.

The same files i have on a real mac without any problem.
So i guess it is a system error, i've installed the app for viewing pictures again but nothing changes. The problem is still there

Please help me, because i dont now, how it happend.
That is since the installation.

Any ideas?

edit: i have using another graphic tools, for example gimp,
the wrong files are showing here correctly! so no file problem.

But i want to use the standart app for using in the finder and especially with coverflow!

Please help
