hey Santefe, I've never used folding@home through wine, but this still looks fairly obvious to me... >> fixme:file:MoveFileWithProgressW MOVEFILE_WRITE_THROUGH unimplemented the key here is "unimplemented". Whenever you see that, it means the program is making a call to something that is present in Windows, but NOT implemented by wine. > Since everyone always says GOOGLE is your friend, I tried GOOGLEing the above error message & while I've found hundreds of links none answers the question Is this something serious, or not? What is it? And is there some windows32 DLL I'm missing I need to import? It is serious, if the application misbehaves, doesn't run properly or doesn't run at all. is the app working correctly??? Also, just a tip, not all DLL's can be migrated to wine. some can while others won't work right, as they may try to access libraries/functions that are unimplmented by wine. - but maybe someone else has more insight into using folding@home, and can give you more specific details. I hope that helps (a little anyway) jordan
