Strange issue with dropdown menus

[trojwl]

For some reason, whenever I right click on something I get a blank box and options won't appear until I put cursor in box and drag it down. All the options (such as "delete") appear and stay there until I do something else. All the options do work.

I must have changed a setting without realizing it.

It happens in Live Mail program, on my desktop, etc. - anywhere where a right click gives a utility menu.

Any suggestions please.

If you right click on desktop and then click refresh .... the refresh stays there, until you do some other action?
