![]() The reason is that this is actually a network adapter, and it's not meant for peripherals like speakers, keyboard, and mouse. The tempoary fix will be to not enable IAccessible2 support at all for suspendable (modern app) processes.Įventually we will want to rewrite nvdaHelperRemote to not deadlock.In the Performance tab, you'll also notice that there is a Bluetooth section, which is probably showing as "Not connected," even though you have connected a Bluetooth device to your computer. Therefore, if the process suspends, you then switch copies of NVDA, once the process resumes, rpc breaks, a winEvent is fired which injects the new nvdaHelperRemote, it waits on the old mgr thread to terminate. However, Windows does not bother unloading DLLs or breaking rpc connections while suspended. The main reason why we see this deadlock so frequently in the searchUI is because the searchUI process is suspended when it is not on screen. This also causes UIAHasServersideProvider (called from NVDA itself) to block. But, if an old thmgrThread is currently terminating, that old mgrThread at some stage tries to send a window message to the UI thread (specifically to terminate IAccessible2 support). However, the application's UI thread (where the initial injection winevent came from) waits until this mgr thread is initialized. When setting up a new inprocThreadMgr thread, the thread waits on a mutex to guarentee that only one of these threads runs at any given time. In the end, it was found to be a flaw in nvdaHelperRemote: Thank you very much for your time and I look forward to any assistance you are willing to provide. It always happens after updating to a new snapshot of NVDA.Īfter restarting NVDA, going to the last program I was in and pressing the windows key, NVDA should recognize the press of the windows key immediately and place me in the search box, and it should read the results automatically.Īlso note, this sometimes happens where it has the delay when opening the start menu, but sometimes the search results still read. ![]() Note that, in order to see this behavior you may have to attempt this multiple times. NVDA seems not to read the results automatically as it should be. Press the windows key again and you should hear "Cortana window.You will notice that you can't up arrow to it. Try to find the search box located just above your account picture.At this point you may notice a major (about 5 to 10 second delay) before it even recognizes that you pressed the windows key, and by that time, it may say pane, or start apps, list, list.Press alt+tab to get to the running programs and focus the program you were last in.Restart it and you will notice that you land in what it says is the task bar.Open a program like Windows Media Player, or Firefox or any desktop program. ![]() This also causes notifications to not read automatically either, requiring at least 1 restart of NVDA, if not more in some cases, to finally get it working. By this point, however, attempting to do a search causes the search results to not be read automatically. Pressing escape, to exit the menu, then opening it again, lands me in the search box. It seems to freeze for a few seconds, then randomly it places me in the tiles on the start screen, causing me to have to press left arrow to get back to the menu portion, then if I up arrow I can't get to the search box. NVDA doesn't always focus the search box correctly in the start menu when first opening NVDA.
