Hi I use FB3.04 and Delphi for writing the front-end programs. I had no
problems with FB 2.5 for years, but now I've upgraded I have problems
every time I run a compile and run cycle.
I get the error - "Error while trying to open the file - the process
cannot access the file because it is being used by another process."

The file in question is the database so I have to close the database
every time I make a change which means I cannot check what's going on in
the event of an error. Then everything works perfectly.
This did not happen with FB 2.5
Is there a setting or something similar in FB to allow this?
The OS is Windows 10, 16GB, SSD drives

Thanks
Alan
