This is with both 0.65 (via repositories) and 0.72 (downloaded from here and compiled/installed manually)

No task switching!

It's fine up to the point that I actually click on the window and give the dosbox-run program window focus; after that, no amount of alt-tabbing or other OS hotkeys will allow me to get back to the rest of the system. This holds true even after the game has exited and it's back to the prompt; I need to type EXIT to close dosbox to get back access to the rest of the system.

Searching here and on ubuntuforums hasn't turned anything up for me. Anyone else run into this? Is there just a weird config line I need to change somewhere? Never has happened in win32 dosbox
