None of the things on that list of crash reasons held true to the map.
Usually, I notice that it crashes when I am doing a lot, such as moving the screen on the minimap and going to order units to do something. However, the map in itself is a very action-based map, so I am doing that all the time, so I really don't see a pattern. One time someone else in my game crashed right before he was about to win, meaning that all the enemy's units were dead and there really wasn't much action going on.
Also, another key thing is that when it crashes, it doesn't do a crash like it does when you see an independent terran command center. It minimizes, and a windows error comes up saying "starcraft has encountered a problem and needs to close. We are sorry for your inconvience." Does that extra fact give anyone ideas?
Any help would be REALLY appreciated.. this is a really weird problem, but it can really effect the game.
As far as getting the map, just IM me or email me, since I don't have a server or anything to upload it to. GreenAppleJones7 and fritfrat2000@yahoo.com.
EDIT: Just crashed on me again.. basically, I wasn't even doing anything, just watching my goliaths attack my enemy's wraiths, and bam, minimized and closed

.
Double EDIT: Big realization! Every single time it crashed, it is later in the game. Well, really, the crash kinda makes it the end of the game... but what I mean is that from what I recall a decent amount of elapsed game time has occurred. It is a 96x96 installation map, but there never really get to be more than 100-200 units existing at the same time...
