I just downloaded Adobe Reader X and the Windows 7 snap functionality won't work with it. It works for all other applications so I think it's an issue with the Reader. Am I missing something?
I don't think it should matter, but I'm using AquaSnap instead of the default AreoSnap: http://www.nurgo-software.com/products/aquasnap.
You can tell that this is an AquaSnap issue simply as right clicking the AquaSnap systray icon and disabeling it makes Reader X follow Aero Snap again perfectly.
AquaSnap needs to add a blacklist option for some applications.
