many thanks Christian - your solution does eliminate the error messages I was getting -- however there was no effect in the screen resolution after running your program.
thanks for the try. I may simply use the custom scale level solution - not ideal but workable. thanks for your input - much appreciated.

>The procedure needs to be called with one parameter, which is the number of pixels for the new resolution to set. You can of course hardcode it and replace tnResolution with the number of pixels. Otherwise call the procedure like this:
