Server busy message

[myotis]

When I open an excel file usng the built in viewer, I get an error message:

"Server busy. The action cannot be completed because the other program is busy. Choose "switch to" to activate the busy program and correct the problem"

When I click on "switch to" the Windows start menu opens, then when I click on the switch to button again, the start menu closes and the excel file appears in the UR file viewer.

This only happens the first time I view an Excel file in UR, or when I launch UR if the active view whan I shut it down was an excel file.

Sorry about this list of issues ;-(
