I now have the problem that when I click on the "Start Menu" and hover over a sub-menu if the sub-menu contains more than x items they are not visible unless I scroll over them.
On a similar note when I open a new window nothing is visble inside apart from the icons after I scroll over them.
When I move a window by dragging the title bar the contents disappear again and upon release of the title bar the whole window disappears until I click on the titlebar and then only the titlebar and border are visble.
Does anybody have a clue about what I am talking about or even better how to fix it?
It would be great if someone did.
