Hi all,

I found a interesting issue though i thought i got it working a long
while ago.

I have 2 computers. One runs Windows XP Pro with Service Pack 3 and the other runs Windows 7
Pro.

Both run NVDA Next 10161, Firefox 26.0 and Flash 11.9.900.170.

The interesting thing is now that on Win 7 i get a buffer when i hit
enter on the flash object for example the youtube player.

On win xp i get no buffer. What i get there is t he mode when you are in
a buffer and you hit nvda+space. so you actually get out of browse mode.

Is this because UI Automation is missing on win xp?

Though i thought i saw it working a longer time ago.

It should be reproduceable pretty easily.

  1. open up for example youtube and look for a video
  2. play the video and go to the flash object with the o key.
  3. hit enter
  4. on win 7 you get to read also the objects content to get for example the time how long its running and how long it has to go.
    On Win XP you don't get anything of those. though you can jump to the buttons and activate them, modify the slider and use the up/down keys to modify the volume.

would be very nice if someone could look into that and also fix it.

Greetings,
simon

I don't know about other embedded objects, but I had the idea that this may well be down to Flash. A lot of Adobe software now needs UIA and seems to no longer work in XP as well as it used to. I'd imagine they are gradually dropping support for msaa. I don't say this is the whole reason but its an idea. I guess you could try an earlier version of Flash, but getting rid of the newer one can be a pain in the neck.

I just tested this on a fresh install with the same configuration and versions. When I hit enter on a Flash embedded object in Youtube, I get a working buffer as expected.

Are you sure Flash is installed and working correctly?
What does NVDA say when you press enter on the embedded object? After pressing enter, can you please move the navigator object to the focus with NVDA+numpadMinus and then provide the developer info from NVDA+f1?

Brian (or anyone else for that matter), are you able to reproduce this?

Also, please try this with NVDA 2013.3. Do you get the same result?

Hi,

I now researched this a little bit better now.

I installed 3 versions of NVDA.

my standard installation which runs as a normal installation which is Next 10169
Then another Next 10169 in portable mode.
And a 2013.3 stable which runs also in portable mode.

Unfortunately they all show the same issues.
Flash should be installed correctly.
I regularly update it.
i might completely delete it and reinstall it again.
if it fixes itself i will report back.

now the outputs of the versions:

Output of standard Next 10169 installation:

  1. hitting enter on a object says:
    "Embeded Object Pane"
  2. the output of the developer info is:

Replying to jteh:

I just tested this on a fresh install with the same configuration and versions. When I hit enter on a Flash embedded object in Youtube, I get a working buffer as expected.

Are you sure Flash is installed and working correctly?

What does NVDA say when you press enter on the embedded object? After pressing enter, can you please move the navigator object to the focus with NVDA+numpadMinus and then provide the developer info from NVDA+f1?

Brian (or anyone else for that matter), are you able to reproduce this?

Did you perhaps disable Flash protected mode at some point (not recommended)? You'd almost certainly know if you'd done this, as I believe you have to edit an ini file.

Hi,

maybe not me but maybe one of my addons.
where should this ini file be?

Hmm. Apparently, Flash protected mode only exists on Vista and higher, so that isn't the issue. That still doesn't explain why the issue occurs on your system but not on anyone else's so far.

XP issues are no longer being addressed. Also, keep in mind that flash will be discontinued in 2020. Closing
