Ah, there's your problem. You don't need to remove the Ace Message System. The reason it was shrinking the window size is because of this line of code:
VARIABLE_ROWS = 21This made it so the variable 21 (ie the variable you were using) adjusted the number of rows in the message box. Looks like variable 22 will adjust the width, too.
If you don't want to use these features, change these lines of code to equal zero, so they look like this now:
# This variable adjusts the number of visible rows shown in the message # window. If you do not wish to use this feature, set this constant to 0. # If the row value is 0 or below, it will automatically default to 4 rows. VARIABLE_ROWS = 0 # This variable adjusts the width of the message window shown. If you do # not wish to use this feature, set this constant to 0. If the width value # is 0 or below, it will automatically default to the screen width. VARIABLE_WIDTH = 0Otherwise, just try using a different variable, and leave variables 21 and 22 reserved for the message system. Hope that helps. Cheers!
