I'm not sure if this has been reported, or if you're unable to fix the issue, but I have realised that a certain crash that happens while playing LH has come up whenever I get a User Account Control prompt (which sometimes occurs when I get a notification of an update to java), the game crashes with the following prompt - DX Error: Invalid Call, followed by crash to desktop. Since I'm not sure where the DEVs check for these sorts of posts I thought I would post it here on the stardock forums.
