Here is a tiny bit of news.
Earlier this week I downloaded the new version of GZDooM, version 2.3.2.
The new version fouled a few things up. The weapons were not switching properly, and the keys were not working at all.
Luckily, 75 took a look, and was able to figure out how to fix the problems.
Everything should be working fine again in the next release.
Of course I still have to deal with this ...
