I have a win98 system running some DOS apps (accpac, easypay, and dataeasy)this system prints to 3 local lpt ports, the problem is when accpac or easypay are accessed for the first time during the day and I try to print it will kick me right out of the program and the error message comes up "This program has performed an illegal operation" I go back into the apps and they will run fine all day, till next day when it happens again.
I have left the system on all night, it runs a schedule back up on colorado backup, it treats it as a restart, because the same problem appears the next morning.
Has any one experienced illegal operations in DOS apps? Any insight would be very helpful, Thanks.
