NVDA hangs on installers after UAK dialogs in Windows Vista. #74

Closed nvaccessAuto closed 9 years ago

nvaccessAuto commented 14 years ago

Reported by mike.reiser on 2008-04-25 18:17 NVDA seems to hang in some dialogues particularly in setup dialogues. Steps to re-produce:

  1. Download the audacity installer and run.
  2. After selecting next, NVDA starts reading the licence agreement. Pressing control does nothing to stop the speech. Tabbing around also does nothing, it just keeps reading the license agreement. You have to wait until it finishes before tabing around to get to the next button.

Do you use UAC with vista? If so, i notice this problem as well. If not, I have never really have had this problem.

Comment 3 by Bernd on 2008-11-08 16:24 I tested it out and it works fine for me on windows XP. WhichWindows are you using? And which NVDA are you using?

I'm using vista, this seems to be related to the fact that nvda doesn't support multiple input desktops here, will have to see what happens when that support is put in.

Comment 5 by jteh on 2008-12-05 02:39 Reporter, what synthesiser were you using when these freezes occurred? Some synths are less tolerant of large amounts of text than others. If it is freezing while reading a license agreement, it's probably related to us sending too much text to the synth and not to multiple input desktop support.

Comment 6 by archenemy on 2008-12-06 02:16 I tested this with espeak and eloquence with the same results. The problem seems to happen after responding to a uac dialog especially Changes: Changed title from "NVDA hangs in some dialogue" to "NVDA hangs in some dialogue which made me wonder if it had something to do with multiple input desktops."

Comment 7 by jteh on 2008-12-17 12:10 The original reporter noted that this occurred on the license screen of installers. This issue should now be fixed. Mike, can you confirm?

@archenemy: Was this the same problem for you? Is it fixed? If it is a different problem, a different ticket should be opened including thorough steps to reproduce. Changes: Changed title from "NVDA hangs in some dialogue which made me wonder if it had something to do with multiple input desktops." to "NVDA hangs on the license screen of installers"

This isn't happening on the nvda installer, I'll test with other installers and will report.

Comment 9 by Bernd on 2008-12-21 23:17 Hello all,

I tested it with the Audacity installer with UAK enabled and disabled. If UAK is disabled, this bug doesn't occur. If UAK is enabled, I must find the UAK dialog box and answer it. Then the installer opens. At the first Dialog box there are a few bugs. You can't use NVDA-Shortcuts like NVDA+t or cancle the speech on a button. Also you can't read the installers welcome message. When I press enter the described bugs are still occurs. The bugs are taken with the complete installers window. Changes: Changed title from "NVDA hangs on the license screen of installers" to "NVDA hangs on installers after UAK dialogs in Windows Vista."

Ah. This is a different issue to the license page issue and does relate to NVDA not yet supporting UAC properly. The problem is that the installer is running as administrator, but NVDA is running without administrative privileges. Thus, it can't access some information, nor can it capture keys from that process. You can get around this by launching NVDA as administrator while running that installer, but you'll need to launch it as a normal user again when you're done.

I'm closing this ticket, as the issue described (with license pages) is now solved (in r2569). Changes: State: closed
