--- Comment #5 from Michael Setzer II mikes@kuentos.guam.net --- On my Fedora 41 and Fedora 42 systems using XFCE desktop manager, I've had no issues with minimizing Pegasus 4.81-pb3.
What desktop manager are you using?
How are you starting Pegasus. Menu or Desktop icon or other.
Might try opening a terminal window, and run program a terminal window $ cd ~/.wine/drive_c/PMAIL/Programs $ wine WINPM-32.EXE
Then try the minimize option, and then open the terminal window and see it any messages are displayed.
I use the following option on mine. WINEDEBUG=fixme-all,err+all
Might want to try WINEDEBUG=+all
But that generally makes a very large amount of output.
