Open and Close Front Panel of SubVI

[trije]

Hi all,

Running LabVIEW 2011 on Windows 7 x64.  I am trying to get a subVI front panel to open from my main FP with the press of a button and then close with a button press in the subVI.  Here is the piece from my main FP that calls the VI and opens the FP 

Plots is defined in another loop and all of the loops are in a flat sequence.  I did it this way because I want it to start with the first press and not stop my main loop from running.  I have moved the item in the left loop around a lot so I'm not sure if I can run that in the same loop as the event or not.  Either way opening the VI seems to work fine.

The problem shows up when trying to close the subVI for the SECOND time.  The code is here:

As I said, the first time I open and close the VI everything works as I expect it should.  I am then able to open it again but now the "blank button" doesn't function and I can't close the window or even open the block diagram to probe anything.  I have been trying to figure this out for awhile, any insite would be greatly appreciated!

Thanks

Found my problem, I had the wrong boolean on one of my other events.  So this seems like a good way to open/close a subVI if anyone is interested!

Its good that you found the bug.

This code may serve as a way for you to compare notes.
