I'm getting the following message when I try to print a 24x50 inch document: "Could not complete your request because of a program error."

I can make any number of changes in the print dialogs and not get an error, but once I change the paper size to a User Defined size (24h50w), I get the error.

If I don't set the paper size, the Print Preview (and print itself) are completely incorrect.

99% of the time I'm printing 20x24 prints and have no problem at all. Again my problem document is 24x50 inches at 150ppi.

I'm using PS CS on a Win2k machine with 2GHz, 1.5Ghz RAM.

Any suggestions would be much appreciated. Thanks.
