Re: continuing research into Outlook 2016 crashes on Windows 7

Joseph,
Thanks, pretty much confirms my guesses though I still have a long way to go before understanding all the components of NVDA. In any case, the control-1, control-2, and control-3 commands in current versions of Outlook at least cause Outlook to crash when NVDA is running, but not when JAWS is running. As you specified this seems to be an ongoing issue and was reported with XP and Outlook 2007 so has been going on for a while if not this specific case. I suppose I could install 365 on my testing Windows 10 VM and see if this is a issue directly related to bad UIA within Win7. I just hate to leave a bug alone when I have source code and can accurately reproduce at will.
Though right now I need to verify that our implementation of Keylock is fully WCAG compliant. So, I might have to stick this away for a weekend project.
Thanks,
Jonathan

Hi, I see. In short, from what I can tell, UIA bridge freezes when trying to obtain something from an app. There are numerous itHub issues regarding this problem. Cheers, Joseph

OK, not quite sure but since my first query did not provide any information I decided to plow ahead.
Basic information from logs are:
Next item in NVDA log is: DEBUGWARNING - watchdog._watcher (15:14:37.355):
Followed by a couple of WARNING - watchdog._watcher (15:14:52.367): Core frozen in stack:
WARNING - watchdog._watcher (15:15:07.414): Core frozen in stack
At which point NVDA stops talking. After getting speech back through another screen reder, Outlook has a not responding message.
When I did a switch from Calendar View to Messages view I also got a debug watch dog but NVDA seemed to be able to clear it out with the following: IO - inputCore.InputManager.executeGesture (15:14:12.845): Input: kb(desktop):control+1 DEBUGWARNING - watchdog._watcher (15:14:14.868): Trying to recover from freeze, core stack: File "nvda.pyw", line 212, in <module> File "core.pyo", line 473, in main File "wx\_core.pyo", line 8657, in MainLoop File "wx\_core.pyo", line 7952, in MainLoop File "core.pyo", line 443, in Notify File "IAccessibleHandler.pyo", line 894, in pumpAll File "IAccessibleHandler.pyo", line 617, in processGenericWinEvent File "IAccessibleHandler.pyo", line 521, in winEventToNVDAEvent File "_UIAHandler.pyo", line 327, in isUIAWindow File "_UIAHandler.pyo", line 315, in _isUIAWindowHelper

OK, some research makes me think that when I use the keyboard shortcut to change from Mailbox view to Calendar View in Outlook that the crash might be related to UIA not being handled correctly. Is there a way I could disable UIA for my copy of NVDA either in intirety or for Outlook just to execute this command without working with the NVDA core? I
So, could I write a Outlook addon that disables UIA when in the SuperGrid or in the INI files?
Thanks!
