Trouble with resolution setting in PRBoom

[Cacodreams]

Well, I tried to ask Colin Phipps this very same question, but with no success, since I got a message telling me that the e-mail couldn´t reach him. So I thought about asking it here: why every time I try to set the resolution to 800x600 in PRBoom v2.2.3 I get a message such as "Z_ChangeTag: freed a pointer without ZONEID" right after starting a new game with Doom2?

I almost always use GLBoom.exe (the GL version of PrBoom) myself, and have never had any problems with changing the resolution. However, when I have used PrBoom.exe I have often got similar errors to the one you mention, often at the end of a demo I have been watching. I'm interested to know the answer to this, because some of my slower computers are less happy with OpenGL.

Anyway, the only solution I can suggest right now is "use GLBoom instead".

Also, cph's homepage provides some other possible means of contacting him.

Have you ever tried to use the PrBoom user mailing list? It is exactly for those purposes ;)
