A different 1C perhaps? If so, sincere apologies.
edit: just found this too - http://int.games.1c.ru/
am I a dissapointed customer? sure am (it's the LOS thing)...will BFC/1C (who apparently now have an American distributor - announcement on SimHQ) fix the product? hopefully/probably...can I wait? yep...would they have fixed it so soon if several "decenters" hadn't posted here? maybe not.
Geez, I run Vista for gods sake (and I like it, so that prolly make me a nutbar)
I have Vista with directX 9 (December update) installed on top of directX 10 (obviously) and have had no problems. I believe they use different DDLs so nothing SHOULD get over written.
