Hi Baj,
That worked, but I now have two problems

1. Pressing on the plus button doesn't do any anything.
2. When I open a new project (.mpp) file it doesnt automatically appear as a new tab. The only way to have a new file open as a new tab is when it's grouped with Excel.
3. When I can get two instances of MS Project visible, after I press the non-active tab the window disappears and seems to minimize...
Thanks for your reply and help on this...
Regards
Trej
