I was running elemental at 1920 * 1080 in full screen , alt-tabed out, came back, and got a DX call crash. For some reason it didn't create a zip file. Here is the debug err file http://pastebin.com/ZeThD6Qp In multiplayer, I ended up queuing 3 farms to build on 1 farm plot. The city thought it had 2 farms, though it only had one. Here's a screenshot illustrating this http://dl.dropbox.com/u/24206199/Elemental_1300904247.jpg After this, I made the resolution of Elementat 1440 * 900, and turned off fullscreen. At this point, while it was running in a window, I could not queue up things to build in my city. I could go into build mode, select things to build, such as huts. WHen I moved my mouse, the building outline appeared more or less as it should. However, when I clicked to queue things up, it would not take it. From moving the mouse around, it seems the interface thought my mouse was in a slightly different place. So it wouldn't take my clicks. This is a problem I have only had running in windowed mode. THank you for the game, enjoying it. Ken
