I have a problem with my computer, and was wondering if perhaps someone would have an idea of how to remedy it. The computer itself is working okay, and I can do work online, access sites, etc, but, this morning, I clicked on something, that caused my blue toolbar that is supposed to be on the bottom of the screen, to end up on its side, with the green start button on top, and the other icons in the middle. I called Comcast, and spoke to a tech, who could not help me. He said that there is some application on the computer, that is locked, which caused the taskbar to end up like this.
If anyone would have an idea of what I might be able to do to remedy this, it would be appreciated. Thank you.
