Incorrect WARNING popup for insufficient memory on x64

Every time I start .901, I receive a WARNING popup incorrectly stating that I have only a small amount (normally within 100-200MB) of 'available total physical and virtual memory', that M&B 'requires at least 700MB of available memory', and that if continuous crashes ensue, to close programs and increase my VM size.



I have lots of memory available, and after the message, the loader comes up normally and I can play without any issues.

Running XP x64 (SP2), dxdiag results:
Operating System: Windows XP Professional x64 Edition (5.2, Build 3790)
Processor: AMD Athlon(tm) 64 X2 Dual Core Processor 4600+ (2 CPUs), ~2.5GHz
Memory: 3326 RAM
Page file: 738MB used, 6460MB available

Could be something to do with the pagefile there - 6460Mb available?!?

I get the same kind of message - i'm running on vista 64 with 4 gigas of RAM. But ti runs smmoth and I simply ignore it.

Looks like it's the 64 bit OS vs. 32 bit code. Safe to ignore it I think.
