using XP and version 3.22-3:
number of bytes downloaded in windows title bar is 
overflowing and going negative and counts back to 
positive.  there is a similar topic posted about this back 
on 07-09-2001.

anyway...i'm not sure exactly when it overflows, but it 
seems to be happening about every 2 GB.  Perhaps 32-bit 
2's complement.
