screen resolution

[Greg Wills]

Hi all

I have developed some programs for a school but have come across a 
problem while testing it on a number of different Mac machines. On 
the older machines the programs do not display the entire contents of 
the card/window. If the resolution is set to 800 x 600 then the full 
card/window is shown. Some of the machines monitors however cannot be 
set to this resolution.

Is there a script that someone has developed that will check the 
monitor setting and either change the monitor setting to 800 x 600 or 
quit before the program runs.

Do windows monitors have the same problem?

regards
