In running the first example from the docs for OpenWindowedScreen ("Example: Fixed screen size with gadgets"), the code begins to execute and then somewhere within the inner Repeat loop, it eventually crashes and the following error is displayed: "The debugged executable quit unexpectedly."

This bug report is about giving a repro scenario. I am not sure what in the window loop is causing the crash. I get the same behavior with my own app, but narrowing the repro down to the PureBasic docs example seems better than trying to copy/paste all my code.

My Repro

Install 64-bit Linux Mint Tricia Cinnamon.
Download and extract PureBasic 5.72 Beta 2.
Run ./checkinstall.sh and then run the recommended "sudo apt-get" command.
--all of the above work flawlessly, super easy install on Linux.
Run ./register.sh
Run ./launch.sh

Search for and paste in the top example from OpenWindowedScreen and press F5 to run.

I can try a different Linux distro if that is helpful in narrowing things down.

Do you happen to be running Cinammon? Or what Desktop Manager are you running? I'll try with the same. Thank you!

Thank you. I tried XFCE and still get the crash on Mint Tricia. I'll fire up an Ubuntu VM and give it a whirl.

[EDIT]: Created Ubuntu 18.04 LTS desktop VM and everything works there. PB 5.72 Beta 2 definitely does not seem to like Mint 19 Tricia.

Debugging PB compiler and IDE internals on Linux has to be unbelievably difficult. Having to support 18,000 configurations

of OS/version/desktop would be brutal. I'll try back once 5.72 goes live and see if they've got it working on Tricia.

Appreciate your help!
