Problem with NVDA and Chrome on HTML pages with many links


Brian Buhrow
 

hello. In using Google Chrome with a squirrelmail web page with many
links, I find either NVDA or Chrome is mis-behaving. Specifically, I see a
lot of errors in the NVDA log similar to the ones below. When these errors
happen, The specific web page in question becomes unresponsive and other
odd things break, i.e. this evening, I couldn't copy to the clipboard for
some odd reason, until I reboot. Is this a known issue, and, if it is,
does anyone know where I can get the fix? I believe I'm running the latest
version of Chrome, Windows 10 and NVDA.
See snippets of the log file below.

Many thanks for any light folks can shed on this issue.

-thanks
