Hi John Scott,

When opening Sage 100 Panel that produces error, examine upper title bar and check for "*" in title of task.
An "*" denotes a Custom Office Panel modification.
Temporarily bypass Custom Office Panel modification by selecting File, Run in Sage 100, and enter *ESC for the program and click OK.
Select "Yes" to enable Escape Trapping and try to reproduce error.
If Error no longer occurs, that will tell you the issue is with the Custom Office Panel modification. If that is the issue, it may be easier to delete and recreate the Panel rather than fix the broken panel.
