I am a retired long time computer professional but have just upgraded to Windows 7 so a novice in that area.
Yesterday, I started having problems with Skype, I had just done something with it and was having mouse problems at the time, double arrows causing strange reactions, etc. so I thought I might have inadvertently done something I had not intended.
Skype would no longer display (be visible) on the monitor so I could not do anything with it. It was on the task bar, would display the mini-window(s) but when one was clicked nothing appeared to happen. [Note: the application may have actually been up but out of the monitors frame. At times I noticed a movement flash going up and off to the left out of the frame.] I tried numerous things to correct this; first rolling back the system to a time before the problem started, installing earlier versions of Skype all with no effect. I also had a second account ID for use on my laptop, if I logged into that account Skype appeared OK.
All of a sudden, after hours, Skype started working correctly again and so far has continued to. However, the problem still exist but has been transferred to "Control Panel" which I can now no longer see and therefore cannot get into to set system functions. All other programs seem to be functioning normally.
Three questions, first, what is this problem I seem to have created? Second, what causes it and is there a way to prevent it? Third, how do I fix it so that I can get into "Control Panel" again and not have the problem transfer back to Skype or some other program?
