eventoracle.cpp error

[bbean]

anyone ever seen this error caused by a registered activex event in LabVIEW 7.1:

It crashes the VI after execution and the error log says:

D:\lvmerc\src\source\execsupp\eventoracle.cpp(392) : DAbort: panel-locking Event callback not in UI!

The interesting thing is that only one of the registered events "cmdended" causes the crash, but the other one works fine. And, it does not crash in LabVIEW 8.2.

I googled and looked at the NI boards, but nothing was very clear about how to fix the problem.

Well you gave yourself in fact the answer already. The solution is to upgrade since it works in LabVIEW 8.2. It is likely a problem in Active X callback event handling inside LabVIEW, where you can do little short from rewriting the ActiveX component, which I assume is no option here either. NI does usually not release bug fixes to older LabVIEW systems once a new version is released (unless you own >500 licenses and therefore have a certain direct influence on the NI decision making).
