I am not sure if the issue is with the browser, the accessibility framework or the screen reader at fault here. I haven't got down that deep on what the screen reader expects from the accessibility framework/browser. also it depends on if the screen reader is built by the browser vendor such as Google Vox, by the OS vendor Voice-Over and Safari or Narrator and Edge, or they are third-party products. As each of these combinations will give different results.

	Hi Sean and Jan

Thanks for your answers.

So I suppose the best thing to do for now is just to report that kind of issues to the browser vendors and cross the fingers for more reliable behavior in the future. 

Thank you.
Lars

Emne: RE: What exactly will trigger a screen reader buffer update?

Hi all,

The actual triggering of the virtual buffer depends on the browser, the accessibility  framework and the screen reader. Depending on how of each these programs communicate with each other determines success or failure. I am aware of specific web sites that visually load fine, while the screen reader/ Accessibility framework and browser don't give the end-user the correct information. The actual defect in this situation appears to be related to the browser. The challenge I see is how to track the issue down?

OK, there are pages that take ages to load (or seem to go into an endless script loop) that will not be read in JAWS. JAWS will only read the page once the page is fully loaded, although everything might be visible on screen. In those cases JAWS+Esc will help.

I have talked to various people in the past about this problem, but I haven't heard of a different strategy to that problem, yet. 

I am sure there are other people on the list that have encountered the same issue. Perhaps somebody else has a solution? I find it quite bothersome, too, but I probably press JAWS+Esc 20 times a day quite unconsciously.
