I would treat this like most problems with apps that suddenly appear.
Go into the preferences folder. In this case, Printer Master prefs would be in your classic System Folder/Preferences. Dump the Print Master prefs in the trash, then relaunch Print Master, and see if that simple trick has helped. Print Master will create a new preference file when you next launch it...
Thanks for the advice on the PrintMaster 4.0. I have the other program also. I teach school and have print shop and Print Explosion. I just Like PrintMaster better. I will try to figure it out, Maybe reinstall? thanks again.
