I'm running the twgs under windows xp
i've been seeing this error messge in the daily logs
Error opening mail box (131)

it's almost as if a user mail box is too full??

any ideas on how to fix this?
when it happens, the user is bopped back out to the start menu and when they try to re-enter..the error repeats its' self..
what seems to force the error is mail back to the attacked user..
I.E. player A enters a sector with player B figs...they attack and then the error is recorded..
