Front panel locked up?

[Synaesthete]

I'm using the System Control UI Suite 2.0 and trying to work with graphs on my VI.  Frequently my front panel appears to "lock up".  I'm apparently able to move around the front panel, however the front panel graphics themselves do not change location.  If I hit "ctrl-A" to select all front control objects, the marquees themselves appear where the control 'should' be.  If I close the VI and reopen it, the controls appear where I moved them previously.  It's as if the front panel image itself is not updating properly.

This does not appear with other VIs. I can get around it by deleting the graphs, saving the VI, renaming the VI, and reopening it.  For whatever reason this sequence restores it.  Once I add the graphs and attempt to populate them with data in run time, my front panel locks up again.

How much data are you trying to populate the graphs with? A few points? A few hundred? A few million? If you're pumping a lot of data into the graphs, then you will see the slowdown you are experiencing, since LabVIEW is trying to draw the data. Have you tried right-clicking on the graph and selecting "Reinitialize to Default" to see if that clears it up?

Over the past few months this problem has continued to be an issue.  It seems pretty hit-or-miss.  I'm using a variety of indicators (a couple XControls), three tabs, a few charts.  The entire front panel locks up, including scrollbars.  I can still "move" the panel and other front-panel objects around, but I don't see the updates.  If I close and then re-open the VI, everything is in the proper location.

Furthermore, none of my front panel objects are storing much data at all.

Hi Synaesthete,

I am curious, do you see the same behavior when using only the stock LabVIEW controls? Have you tried replacing the UI Control Suite System Controls with the stock LabVIEW controls and seeing if the behavior still exists?

Also, do the controls only lock-up when in edit mode or do the controls become unresponsive while executing the VI as well?
