Hi,
Before we get into debugging things, can you try running with add-ons disabled (press NVDA+Q, select "restart with add-ons disabled") and see if NVDA slows down?
Cheers,
Joseph

Joseph, I do not know the command for "debug lockdown". I will gladly do that for you if you can give me the command because the latest update on either Thunderbird or something else has definitely caused the program to be sluggish.



Thanks so much for all you do. I am definitely hoping to donate to NV Access some time this year.

Hi,
Is this the case for people using old Thunderbird releases? If not, this might be something to do with TB 75. To better understand this though, I need a debug log (restart NVDA with debug logging enabled, use Thunderbird, as soon as you hear "message deleted", press NVDA+F1 to open log viewer, copy and paste everything as a private email to me as debug log will give you all sorts of information such as keys you've pressed).
Cheers,
Joseph

Good Morning: Has anybody else noticed a change in Thunderbird after making the most update of Windows Essentials? . This would be version
20.04 with NVDA 1903. This problem occurs on an insider version of windows, so, it might make a difference. When in thunderbird I hear that one message has been deleted, when deleting a message before going on to read the next message.
