>We have tried blanking out the Tag and Tag2 fields. It did not change things. There are 4 machines that are identical using this app. One gets the printer driver error consistently. The others do not. They all have 128M memory. Problem started when they loaded new print drivers for a new printer. No app change made at the time. Is it possible for Windows to allow the print driver and foxpro to access the same memory?

You've to modify Expr field also. See mesages I refered for details.
