I have not added any new programs.
However, the computer is linked to a server where Microsoft (without my permission) downloaded IE 7, which, as you know, is responsible for a host of problems.
Also, on the desktop, if I right click on properties and go to display and open the help file, it stays onscreen for a couple of seconds and then closes by itself.
What could cause that?
Q: If you open an application through the Start menu, does the mouse work correctly in the applcation (such as Word or IE)?
A: The programs won't open through the start menu.
Q: Is it only the desktop that is disabled?
A: I am not sure what you are asking, but I can't get any programs started.
Q: Have you added any new applications or utilities prior to this starting?
A: Except for the Microsoft intrusion, no.
There are two guaranteed rules of success: First, never tell everything you know.
