Buildings doesn't rotate

[alex_spr]

Hello! Sorry for my poor English.
I've bought a new PC (Win7), everything is Ok, but in SC4 (license from Origin) buildings doesn't rotate by Home/End keys. I mean, they rotate for a milliseconds and turn back in original position to road. I need to press Home and Left Mouse Button very quickly to catch right orientation.
Other pieces, that doesn't need orientation to road, place normaly.
What's wrong?
Thanks.

Maybe I'm going to give a disappointing answer, but I think this is the game's normal behaviour. One just has to be quick, and if that doesn't work, I usually bulldoze the road, place the building and rebuild the road. Perhaps it's that the faster the computer, the faster it turns the object back, I don't know anything about that.

By the way, no problems with your English, it is completely understandable.

Themistokles, thanks

The problem goes away by itself  That's strange, but cool.
