Problem with front panel not responding

[Karin_Hellqvist]

Hi!

The problem that I have is that the front panel of one of my vi's is not responding to user actions until the window is minimized and then opened again. The actions tried are marking controls or trying to scroll the vi window. For example if a tab menu is clicked if it not changed until the window is minimized and then opened again.

The vi has worked fine, but after some changes in the code behind it it doesn't work. After deleting most of the code it works again.

I have had the same problem a couple of times with differnet vi:s. The run time menu works.  Also, there is no difference if the vi is running or not. It doesn't work in any of the cases. I can also add that I have only had the problem with vi:s that has rather much code behind themselfs (in many levels of subvi:s). I'm running Labview 8.0.

Have anyone seen this problem before? i would like to solve this problem without deleting all code and then bulding up it again.

Best regard

Hi Karin,

Could you provide us a VI where this problem occurs? It would be good to have on VI where this happens in order for us to be able to reproduce and eventually report it to R&D.

Thanks in advance!

Hi Caroline,

Unfortunately I don't have the VI that didn't work saved anymore. I noticed that it was the function Current VI's Menubar that was the problem. By replacing it with the same function again the VI started working. I had that function in the VI a long time before it stopped working properly. I must have changed something else in the VI that affected that function. Maybe I changed the run-time menu, or opened a new run-time menu for that VI. I don't remember exactly.

Best regards

Karin
