Accessing pulldown menu halts VI?

[gstanczak]

I have a producer-consumer type VI with a custom menu.  Pulling down a menu from the menubar and then pausing before completing a menu selection will cause my VI to halt when it comes to a particular subVI in one of the states inside the consumer loop.  The VI will continue through other states that have DAQ functions and other subVIs even with a pulldown menu accessed, except this particular VI (image attached).  The particularly subVI with the issue dynamically calls a VI that loops a short .wav file.

can somebody tell me why it is halting and what needs to be done to prevent it?

Thanks,

I was surprised that just having a pulldown menu open, without making a selection, would affect in any way the rest of my VI.

LabVIEW has a component called the root loop which requires some things to run in it. The menu code and the Run VI method both seem to be included in that list, so they're serialized. I don't know if there's any way to work around this other than not keeping the menu open. See here for a similar problem.
