Re: [orca-list] Update on the situation with closing apps hanging Orca: Please resume testing

[Max <heavy9922 gmail com>]

Hi Joanye.

Now "orca" really close and does not hang.
I immediately managed to catch the oddity that occurs when you close the 
"gnome-terminal". Here's what I found at the end of the debug file. If 
need be, I will send debug file completely.
