We are using LabWindows 2010 SP1 on Windows 7 and Windows 10. Our application was upgraded from LabWindows 7. Never had this problem in LabWindows 7.
We have are having a problem that the EVENT_VAL_CHANGED is not being sent to our callbacks after a ring selection has been changed. This happens in release mode and when debugging the program in the IDE. This happens with more than one ring control but is somewhat random when it will popup (problem happens 5% of the time).
Ring control mode is Hot in the UIR. No SetCtrlAttribute calls were made on the ring control.
Steps:
1) Change ring selection from default selection, no callback
2) Change the ring selection back to the default selection, no callback
3) Change ring selection from default selection, no callback
4) Change the ring selection back to the selection value, no callback
5) Change ring value from default value, the program does get a callback with EVENT_VAL_CHANGED
What could cause the event to be lost?
