I am constantly having to delete the CCH files with working with DF 20.0 and the PSQL driver 20.0.1.99. When working with the DF 20.0 (build 152), I am constantly having to delete the CCH files due to the error "DFBTRERR Cannot read from cachefile".

One way I recreate the error every time is:
1) Compile my app and I get the error, I delete the CCH files and then the app will run.
2) Go to dbexplorer and try to open one of the files the app from #1 above opened, and I get the error.

Then, go to dbexplorer and the file(s) will open. Now go in reverse:
1) One of the file is open in dbexplorer.
2) Open one of the files not being used.
3) Go back to the studio and run the app again and I get the cachefile error.

This happens EVERY time. It is getting very old very quickly. Any suggestions? Really just recently started with DF 20.0 and it has been happening constantly.
Thanks
Mark
