Placing an XControl in the BD crashes LabVIEW

Aitor - I noticed your post and just dropped a simple XControl into the BD and it did not crash LV (8.2). It simply did what I expected...create a constant of the data.ctl data type.

What does your xControl do?

Nothing special, in fact I also tried it with the xctl in the LV examples (dual thermomether I think it's called, is placed in examples/general/xcontrols) and the behavior is the same: crash boom bang. Did you tried with 8.20 or 8.2.1?

With thermometer example, I don't see a crash with either 8.2.0 or 8.2.1.

Aitor - ditto wrt AQ's results. No crash with the dual themometer in 8.20.

Feel free to send me your Xcontrol and I'll try it.

Are you doing anything that NI does not recommend ie. using globals, functional globals, additional shift registers etc? What is the datatype of the xcontrol?

Trust me, I do nothing: I select the Thermometer XControl that ships with LabVIEW 8.20, I hover it over the block diagram and see something strange like an empty lowered box

And when I release the mouse, crash.

I don't think the XNodes are related to this (though I have seen strange errors in XNodes when trying to create an XControl input, so who knows).

Just to be sure we are doing the same, I don't mean to drag an XControl from the front panel to the block diagram (that works) but placing it directly in the BD. Steps: in the BD right click -> Select a VI -> go to the XControl folder -> select "All files" to see the XCtl -> select the XCtl file -> place in the BD.
