Hi, Tim
This problem normally occured when your VI constantly switch back and

functions or operations, which running in the UI thread:
- Property Nodes
- Menu Control VIs
- VI Server
- Thread Unsafe CINs or DLLs.
Be sure, that all of

The confusing thing for me is that S would have FOUR callers (and thus

OK - that occurred to me that there could be 4 values of V, but I

I had always thought about it in terms of callers - there is one V for

The thing you have remember is that even though there are only two

will have its own data space within =91M=92, and as it loads its subVIs,

I can't explain it either but if I resize the tab control by even a
slight amount, the tabs get displayed correctly.
Charts and graphs are indicators, so you have to look at it's source.
If it is a waveform, use the waveform unbundler in the waveform
