First of all I wanted to congratulate for your great and useful job with portable OpenOffice!
This problem I am reporting occurs with version 4.1.1:
If I open a file (for example a Calc file or a .doc document), thus OpenOffice is already running, and then I double click on another OpenOffice file of any type from Windows Explorer, I receive this error:
"another Apache OpenOffice is running"
So the thing is that, instead of just opening the second file, it tries to re-open the whole OpenOffice thing every time!
Thank you very much.
All the best!! (y)
