[orca-list] virtual Carret is not stored in Minefield when returning from another window

[Victor Tsaran <vtsaran gmail com>]

Hello all,
Apologies if it is not OK to post bugs to the list, but I wanted first  
to see if others have similar problem.
I noticed that when reading with Orca in Minefield and with several  
windows open, Orca loses virtual carret when returning from another  
window (with ALT+TAB) and does not allow to navigate unless a TAB or  
SHIFT+TAB is pressed.
Specs: Ubuntu 7.10 with the latest SVN Orca snapshot; latest nightly 
build of Minefield; AMD Athlon 3200  CPU; 2GB of RAM.
Here are repro steps:
1. Open a GNOME-TERMINAL window.
2. Open some page in Minefield.
3. Start reading the page and at some point switch to the terminal window.
4. Now return to the Minefield window and try to arrow up and down.
Result: you will get silence and no movement is performed.

Can anybody confirm this behavior?
Thanks,
Victor
