Hello
If I can just add a little.
Ctrl S saves.
Alt S saves all
Ctrl Shift W closes all open items - hopefully this also means they are written to disk.
So I always Alt S and then Ctrl Shift W before closing and I run them both about every 10 minutes while I am working
I also have the Force Flush" option ticked and the Auto backup set to 5 minutes in the General Windev Options
You can rely on Windev crashing at least once per day and more frequently if you make code changes while the debugger is running.
Regards
Al
