I run Windows 7 RTM on Parallels without any problems. However, the built-in Windows picture and photo viewer only shows blurred images. Only when expanding images with the Windows viewer to full-screen or actual size mode (the viewer, not parallels) does it show the image file. I tried running Windows both in the Parallels Windows mode and in full-screen mode with Parallels Tools automatically changing the resolution, but to no avail. I am pretty sure this has something to do with the resolution that the Parallels virtual video card passes on to Windows and its viewer. I played around with the virtual video settings, but that didn't resolve this issue. Does anyone have a similar problem? Remarks and ideas more than welcome!
