Trouble with dissappearing/re-appearing troops...

[danstudentvcc]

Hello. I hope you can help. With the CD version game I encountered no trouble. However now that I have patched up all the way to the turret correcting 2.51 patch I have encountered a vexing problem.

When the AI's forces take fire and losses in their infantry units from my AFV/APC's they first dissappear without any related message then reappear. I had one encounter last nite where they dissappeared completely but reappeared when I selected another vehicle two hexes away with the same vis on the same hexes. Both units were vision 40 and both could see the unit once it reappeared. There was as well no message to indicate why they dissappeared on this occaision nor in the past.

Query: Since this is new for me:
Have I installed incorrectly? [I had completely reinstalled Win XP hence WinMBT was fresh - I rebooted after each patch install].
I do run other programs at the same time as the game; hence could this be the factor -- ie low in ram? processor errors?

Thanks

Gus
