So about a week ago, my right click completely stopped working, it works in internet browsers, but anything that has to do with windows it shows me an error- "The specified module could not be found. C:\Common Files\Adobe Version Cue CS4\Client\4.0\VersionCue.DLL" thats the error when i right click, this happened after a failed installation of adobe photoshop. But now more recently a couple of days after that my copy and paste shortcuts stopped working and my delete key won't work it throws errors at me to, and now yesterday none of my resolutions above 1024x768 don't work either it just goes to a black screen, and i know for a fact this monitor supports it because it was running it 2 days ago. ????

and i forgot to add, my drag and drop was the first thing to stop working sorry bout that. also, the drag and drop was the only thing out of all of these that stopped working before the failed install of Photoshop, so it may be two different problems at the same time

ok i have fixed the adobe issue, but i still cannot drag and drop

Doesn't sound good ... drag and drop is a built-in Windows feature, which is active in different programs, like inside the File Explorer, on the desktop, etc. etc., but not in a web browser. I guess some program (installation/removal) messed up that part of Windows, which can be very annoying. Try to re-install software you had before, just for the sake of fixing the issue.

i haven't uninstalled anything except adobe, but this problem showed up before i even installed that software.

surprised first thing recommended wasn't start>run>sfc /scannow>ok (note the intentional space after sfc and before the forward slash). Regards and hap-e-trails, Steve Hopper
