Some Additional things for you Lemmy... I'm using Win7 Ultimate x64 1. I do not get the X on the splash screen 2. I don't get the double lines. 3. the Curve of pipes breaks (on any tech, but this atomic theory) if you move a tech to the left of it's starting position, but is fine if you move it to the right. Moved to the left http://s880.photobucket.com/albums/ac3/Evil1rob/?action=view¤t=MovedToTheLeft.jpg Moved to the right http://s880.photobucket.com/albums/ac3/Evil1rob/?action=view¤t=MovedToTheRight.jpg Not seeing any other oddities atm, but I'll go back through the last couple pages of the thread and see if I can duplicate any of the bug reports.
