I'm using report generation VI's to generate my report (standard report). If I make an application at my development PC (LV 6.0.2 Win-NT 4.0 SP6; application builder 6) and start the EXE-file, there are no problems. I transfer the software (installer) to the target PC (Win-NT 4.0 SP6; run time engine 6.0.2) and start the print subroutine in my program. When I leave the application I have still the LV-Task in the Win-NT task list. I have to start the task manager to stop it. It happens only if I use the print subroutine ( with the report generation VI's) in my program. I made a test with the same subroutine but switched to html output, the task list is emty after leaving the program. Do you have any idea?
