#553 Recovery from full-screen mode stopped working

[Aubrey Jaffer]

I have DOSEMU 1.4.0.8 working in Ubuntu 15.10 on Lenovo-Z70-80 and DOSEmu 1.4.0.1 working on Ubuntu 12.04 on HP-dv7t. Full-screen mode (C-M-f) works (running OrCAD IV) on both systems. While the older system (1.4.0.1 on Ubuntu 12.04) recovers nicely from full-screen mode, the newer system (1.4.0.8 on Ubuntu 15.10) shows a tiny portion of the screen magnified, and C-M-f has no further effect.
