For Moo2. I have played serveral games now and I have been running into the same problem over and over. I'd crash while retreating from combat.
Seems that if you retreat from the left most grid column in tactical combat (at least on my 2 win98 systems) you'll crash to desktop everytime. III haven't gone too far out of my way to test this, but it seems pretty consistent.
Well its an easy enough work around ( just don't retreat back there) but it was SUPER annoying

for several play sessions for me.
For those that are wondering just what on earth I was doing back there anyway... I was using mass frigates to lauch MRV nukes at my early opponents and I was running from the missles/fighters coming at me. Just trying to buy enough time until the starbase/ship/missle bass ate its volley of missles.
