Actually the xmode /w4 par=1 is correct.  I believe Charlie is trying 
to create a VDG window in /w4.

The display command is incorrect.

Charlie, I tried your problem script file.  It behaves the same way on 
my computer (I take issue with your use of the term "lock up" which 
implies a solid crash.  The CoCo 3 doesn't crash; you can still hit the 
CLEAR key and switch windows, except there is no shell and you can't 
type any commands).

I've traced the problem to a issue with shell+ and how grfint and 
windint handle window I/O.  I'm not sure why it's a problem at the 
moment.

Here's an altered version of your original startup script, with 
Robert's recommendations, as well as my own:


link shell
load utilpak1
wcreate -z
/w2 -s=2 0 0 80 24 0 2 2
/w3 -s=2 0 0 80 24 0 2 3

display c>/w2
display c>/w3
shell i=/w2&
shell i=/w3&
xmode /w4 par=1
shell i=/w4&
chd sys
merge stdfonts stdptrs stdpats_2 stdpats_4 stdpats_16
display 1b 32 0 1b 33 2 1b 34 2 c

Notice the display c commands sent to /w2 and /w3.  Just this single 
byte of output to the window appears to abate the problem.

Also, the blank line after the second wcreate command is important.  
This tells wcreate (which is running at that point) to stop.

Try this and let us know.
