Dear core developers,
I have finally found out The reason, why my braille device button inside 
Tieman Braille Voyager could not be used while runing Windows XP inside 
virtual machine.
I had to let NVDA screen reader to blink with The Braille device cursor.
If cursor blinkink have been set for 1000 milliseconds, i had to wait 
more seconds untill NVDA reacted on The braille key stroke.
If cursor blinkink have been set for 200 milliseconds for example, i 
could get The buttons work very fast.
But i can not set this value for too lov value, because Wxpython, which 
is containing software pump, which is pumping The other parts of The 
NVDA core components to work in The multitasking mode have also timer 
set to some milliseconds value, so i can not let NVDA to blink with 
Braille cursor with The same speed as a Wxpython software pump cicle is 
set to.
I would like to thank You, that You have develop Virtual box so 
effective, that The CPU s not being over burned while running Windows XP.
MY CPU fan is working at The lovest speed even Windows XP is running for 
many hours inside virtual computer.
