Timed loop in LabVIEW DLL does not exit nicely

Question

Hello!  I have what I think is a simple timed loop in LabVIEW that exits after 100 iterations by throwing an error, and letting the loop "stop on error".  This works fine when run in the regular LabVIEW environment, however, when compiled as a Dynamic Linked Library (DLL) and called from LabWindows it forces me to terminate execution, rather than exiting nicely.  What's more, it seems to quit the actual Virtual Instrument call just fine and proceed to the next line of code, but when my main() function in LabWindows completes there must still be something not cleaned up that is causing it to not exit nicely.  Any ideas?   I've tried adding a call to QuitLabVIEW and that doesn't seem to do it.
Thanks in advance - hoping you'll point out some really easy mistake. )
Attached is a picture of the timed loop.
Below is an excerpt of code from LabWindows:
 int main ()
 CallMyLabVIEWDLL();  //This line successfully launches and closes the window for my LabVIEW virtual instrument
MessagePopup ("My Title:", "This happens after the call to your LabVIEW DLL");    //This popup shows up - indicating the call to the DLL has completed
//But after the code has completed LabWindows still says "Running", rather than shutting down.
    return 0;
Solved!

Update:  I tried the simplest possible "While" loop and it works.  If I replace it with the simplest possible Timed Loop, it doesn't.  (See attachments.) 
The only thing I could find in a search for why a time loop would break a dll is a patch for lvalarms from LabVIEW 8.5.1 .... I'm running LV 2010 so I don't believe that's an issue.  Correct me if I'm wrong?
Thank you!
