Happens a lot using Roxio Video editing and some other programs with sometimes the message "explorere.exe" stopped responding and blanks out my desktop. I use Task Manager to restart Explorer.exe application. The right click problem as quit showing up for now don't know what I did to eliminate that situation. After several of these events I restarted the computer from shut down status as opposed to restarting it.
First sign of problems since I did a clean install of Windows 7 64 SP1 back several weeks ago when you were helping me with another weird problem.
Thanks for your response and I did run Tweaking AIO with all items checked and maybe that fixed the right click problem I just don't know.
