<UFT Support Tip>Break points exist even after close and reopen the script.
This is considered as the expected behavior in UFT 11.5x/12.0x, this is documented at UFT User Guide:
UFT User Guide
Breakpoints, Page 758
"Breakpoints are saved with your document and are maintained even after you close and reopen UFT. UFT maintains the breakpoints inserted in a test or component per user on
a given computer."
[Workaround]:User could use ctrl+shift+F9 to clear all breakpoints before debug testing.
