PDF Architect 6 Pro freezes on close

I just upgraded from 6.1.23.1856 64-bit to 6.1.24.1856 64-bit on Windows 10.
Now occasionally when exiting, the program freezes and the cursor is spinning. We need to go into task manager and exit the program. With the previous version, this did not happen (but we were on Windows 7).
We will be working with large PDF's (100+ pages) and insert/modify pages, then save and eventually close. Not all the time, but occasionally we will have this issue.
Can we revert back to the previous version to see if it happens? (6.1.23.1856)
We have tried uninstalling and re-installing with no success in fixing the problem. I know - because this does not happen all the time, it may be difficult to re-create.
What can we look at to try to fix this issue. I have seen other posts with same type of issue but no clear solution.
If you need more information, let me know.

Hi,

sorry for the trouble. This forum is maintained by the PDFCreator Support team and while we can help with some of the more common PDF Architect issues, I am afraid we won't be able to help with this.
Please contact the PDF Architect Support team directly via https://www.pdfforge.org/pdfarchitect/support
and they will look into the issue.

Best regards

Robin
