I am curently having a problem opening excel workbooks on my computer.

These are files i use regularly which are shared with other users.

The problem is this: when i open them excel opens up like it shoul dbut
doesn't display the document, it shows a blank screen like if you open excel
before starting a new document. if i then minimise it the document appears in
the windows and i can work on it like normal. i'm having the same problem
with word as well.

i am using office 2007.

anyhelp would be great

thanks in advance
