Hmm. I see that too. I'll look into that.

The LCD module does not support every single feature of the LCD. In this
case, gpsim is telling you that two commands were recognized, but are not
supported. A third command was not even recognized.
Now, even though the gtk error is displayed, the LCD module does run
correctly. I suggest trying out the example software that is in the
lcd-0.1.1/examples subdirectory.
Invoke the example like this:
gpsim -c lcd_mod.stc
That will start gpsim, load the example, load the lcd, hook everything up,
etc. Then when you run it you should see the message "GPSIM WROTE THIS"
printed on the display.
If the example works, then either your software is using a feature that is
not supprted by the gpsim LCD Module or there is a bug in your code. If
it's the former and prevents your code from working, then please let me
know and I'll try to fix it.
Also, I'll look into the problems with gtk... (BTW, there is a graphical
bug in the LCD module. For some reason all of gpsim's windows get painted
with an LCD green background when the LCD module is loaded. I think I know
why.)

Scott
