htop memory usage error

I

instain

I've had htop installed on two different machines now, one running FreeBSD 6.3 and one 7.1. On both of them htop reports memory usage that is off by a factor of 1024.

Here's an example comparing top to htop

top:
Code: 
  PID USERNAME    THR PRI NICE   SIZE    RES STATE  C   TIME   WCPU COMMAND
61920 apaulsen      7  52    0   258M   199M ucond  0   0:00  0.59% firefox-bin

htop:
Code: 
  PID USER     PRI  NI  VIRT   RES   SHR S CPU% MEM%   TIME+  Command
61920 apaulsen 128   0 270608M 209856M     0 S 11.0 100. 23h24:07 /usr/local/lib/firefox/firefox-bin

Any ideas on how to fix this?
 
I found the problem and attempted to push a patch upstream. In case anyone is interested:
