We have been stuck with version 2017 of PowerBuilder because every recent version of PowerBuilder has caused random crashes in our application.
During recent testing after migrating our main client application to PowerBuilder 2022 it became evident that the cause of the crashes was a currently running PowerBuilder application built with an older version of PowerBuilder.
I have been able to consistently reproduce the crashing behavior as long as I have an application built with an older version of PowerBuilder running before I start the PB2022 application. I have reproduced the behavior with an application built with PowerBuilder 2017 and also an app built with PowerBuilder 12.5. It does not appear to matter what application I am running, we have several, it only seems to require that the application was built with PB2017 or earlier.
We release our client application every year with an updated database. If we release our 2023 application built on PB 2022 it would be running concurrently with older versions built with PowerBuilder 2017 or earlier. This is not just an academic problem, it appears likely to affect our clients and be a serious issue.
I have not been able to duplicate the crashing behavior when running my application from the PB2022 IDE, but I can duplicate the behavior running the compiled app on the same machine I use with the PB2022 IDE.
We all run on recent versions of Windows 10, I will test on Windows 11 but have not yet. The PB2022 app was built using the latest MR, as you can see from the Event Viewer info:
