Description:
Upgraded suite to 7.5, now all of my calc xls files will say that they are in use and I can copy or open in read only.  WHen I make a copy then delete old one and replace it with newer, it will end up saying that it is open by unknown user and can only read only.  I rebooted the system, and repaired the install but problem is still there.  It appear that a "in use" flag is being set by default each time.  

Some of these file haven't been accessed in months  

Steps to Reproduce:
1. try to open any existing xls file
2.
3.

Actual Results:
double click to try and open an existing 

Expected Results:
pop up telling me that in use and I can open read only or copy
