LabView freezes up when I try to get the property panel of a variant constant.

[denull]

I am trying to create a cluster which contains a boolean and a variant. The idea is that I want to pass this in a Q between a child window and a main window. I create a cluster, I put a boolean constant inside it. I then find a to variant data function and right click on it and select create->constant. I then drag this variant constant to the cluster. I am trying to give it a meaningfull name and a description. But when I try to open the properties panel, LabView freezes up (full CPU usage). It stays in this state for a while (possibly forever).

I can open the properties panel for this variant when it's sitting outside the cluster. But when it's inside, it causes LabView to crash.

(LabView Version 7.1 on WindowsXP)

I get the same behavior in 7.1, but it works as expected in 8.0.  I am also running XP.

This has been reported to R&D (# 3D75PAQ4) for further investigation. A possible workaround is to name the variant constant before inserting it into the cluster. Alternatively, you can place the variant initially as a control on the front panel. Variant controls are located in the Array/Cluster palette. You can then name it before changing it into a constant on the block diagram.

This behavior has been fixed in LabVIEW 8.0. Thanks for the feedback!
