Staging interface freezes when dragging

[BattleMetalChris]

With the new 0.90 update, the game has started freezing for a second or two whenever I try to drag items in the Staging interface. Everything else works fine, and there are no freezes any other time.

Say I want to move an engine ignition action to a different stage - I click and drag and get around a 1 second freeze. Once the freeze stops there's about a 50% chance that the item will have moved correctly, otherwise it doesn't move at all and I have to try again (which of course triggers another freeze).

This happens both in the VAB and whilst in flight, and both with mods and with a clean KSP install. This never happened before 0.90.

Windows Vista 64

I'm not an expert at this stuff. Your RAM seems pretty good. I think mine is 4GB RAM, and it never freezes for me. So I don't think that's the issue.

Either it's because it's a Vista, or your graphics card/drivers.

Please see the stickied Stock Support thread. We really need more information to look at -- log files and DxDiag would be a good start, I think.
