I have a strange bug that we've observed maybe only 4 times ever (out of thousands of hours). I have a table control on my main panel that has maybe a dozen columns. Once UUT are testing, this control is updated once every 4 seconds in a variety of ways.
- 1 row at a time is boldened and several of its columns are updated (both text and numeric)
- The table is interactable, such that user can right click on it for more control.
When the bug happens, the table is "frozen" in one position, not appearing to update. Yet with inspection, user can see that all UUT are still actually testing, cycling, etc. Other panels are responsive. Other controls are responsive. Panel itself is responsive.
If I click on my Login menu item, which forces a massive restructuring of the above table control, it then magically returns to working order. In other words, I don't have to shut down the app to clear the bug.
Ideas?
