running several Mark windows in parallel

[Eldar]

Hallo,
I am thinking about running several copies of Mark one one computer (Windows 7, 64bit)
1 Mark copy uses only 22 mb memory and 13% of processor time om my machine.
I ran second analysis (from another folder) and it simply added another 22+13. So theoretically I can run 7 copies of Mark in parallel without any problems.
Then I hope to combine results into one database using a new option implemented by Garry last week: viewtopic.php?f=1&t=1715#p5036
Is it correct way and do Mark copies work really independently?

Thanks,
Eldar
