Cannot load connector pane

[deyyoung]

Has anyone else had this error before?  I've asked tech support but they had not seen anything like it either.

System:

Windows 7 Professional (64 bit), LV2010 (v 10.0f4, 32 bit)

Repro Steps:

1) Create a new VI (any method)

2) Right-click on icon and select "show connector"

Expected Result:

Connector pane is displayed

Actual Results:

Error message - "LabVIEW: Cannot load connector pane"

Workaround:

Click OK on the error message.  The connector pane then loads and everything works just fine.

This only happens the first time I open the connector pane on a VI; it never happens again after I've opened it (even after saves, etc).  Tech support had me try the f4 patch, reinstalling/repair LV2010, and I even did a mass compile for good measure.  It's not a real problem (I just click OK on the error and go about my business), but I am curious to see if anyone else has seen this kind of behavior before.

I also have Windows 7 64 bit and LabVIEW 2010 32 bit and this does not happen. I am however using 10.0f2 and not 10.0f4.

So if you have some archaic line in your LabView.ini file (perhaps from way back in the 6/7/8.x days, and it's simply been copied over after each and every upgrade, then copied over to new PCs) and it looks something like this:

defaultConPane=4185

Then you could be trying to load a connector pane that does not exist.  Perhaps it should have been 4815, or something else.  In any case, delete said line and all is well.
