I’ve used WindowBlinds of years, but have run into an issue very recently, with wblind.dll causing a media app, DVDFab’s Media Player Professional 3, to crash upon accessing any of its features, including menu. The crash report cites wblind.dll, and indeed, if I rename that file, the media player runs without issue. I see several versions of wblind.dll in the WindowBlinds folder. Do I need the original one? I’m running Win7 64.
