From time to time when I navigate in Windows (Win7x64) the right click mode will flash then disappear. When this occurs I usually have to re-boot to restore functionality. Does anyone have an idea to what causes this to happen periodically? What I'm talking about is whether it is in deskop mode or browser (it makes no difference) when it happens it renders the mouse more or less un-usable. No matter what type mouse I use it re-occurs or if I switch USB ports it still does this. I've checked mouse settings and they are what they are suppose to be. I've read posts about this but none have pertained to my issue (that I know of). Is there another setting I'm missing or is it the 'nature of the beast' in windows?
For instance when I want to restart and click on the Windows Start button and then try to click on the arrow on the Shut Down task bar it'll flash for a micro-second or if I right click on my Desktop the context menu will micro-flash. What causes this glitch?
