Well now do I ever feel sillllyyyyyy I am so sorry...
That would look rather large on a 24 inch monitor.. Bet you can see everything though..
There is not a setting to define the opening size as you are wanting. I will pass the idea along to the AW2K tech team though.. Although, I do think that AW2K is suppose to remember the position and size of where you last closed the program.. I'll check for you and find out.. I know it does on my computers But I do not have any 24 inch monitors so I'll ask.
