I pulled a goof last night while debugging a program. I ran the VI to test some changes, and while it was running I closed some extraneous LV windows that were still open. But in the process I accidentally closed the block diagram window of the VI I was running, and the stop button was only shown on the block diagram panel. As a result, I couldn't stop the VI and had to hit ctrl+alt+del and close the program. I lost about a half hour of changes. Fixable, but frustrating!
I'm going change this VI so I still have the start/stop toolbar showing on the front panel when it runs, but what could I have done last night to stop the VI?
