gzdoom, zandronum refuse to close when I quit

[invictius]

Even though they're run fullscreen, upon exit I get a full-size windows showing the title screen and I have to end the task. Zandronum 1.2 and the latest version of 2, gzdoom 2.0.9999

First of all, both your Zandronum and GZDoom seem outdated. For Zandronum you should be using 2.1.2 and GZDoom should be either 2.1.1 or 1.9.1
