[Coco] Strange behavior in MESS

[Bob Devries]

If I try your programme in the VCC emulator, it can be run multiple times 
with no ill effects.

WOW Did that e-mail get MESSed up (pun intended). Let's clean it up so we 
all can read it. I don't know what happened.

Hey all,

Has anyone ever seen this before? I'm writing a game in assemblers using 
MESS to debug. I made a small function to set all the palette registers to 
black (screen blanking). In mess, it seemed the CPU (emulation) was locking 
up. It wasn't. So, I wrote a test program in basic and something strange is 
happening

10 FOR X=0 TO 15
20 POKE &HFFB0+X,0
30 NEXT

I run the program and all is well. The screen goes to black. I blindly type 
RGB and everything returns as expected. Run the program again and BLAM!! It 
appears to lock up. But, it's not. You blindly type anything (CLS then 
"Junk" then ENTER). The screen doesn't show anything but the original RUN 
command. Blindly type RGB and the locked up screen goes away and the screen 
with the CLS and "Junk" displays.

Can anyone duplicate this or is it just me?
