I've just come back from not using ultra for about a year and I've got issues with the editor. This is a new project, new map. After I insert anything into the map, such as a box, or create terrain, the editor locks up. I can no longer navigate or move in the perspective view, or any of the 2D views. I cannot create any new boxes, can't undo. If I press new map, and click don't save, it doesn't create a new map. I can still navigate through all of the controls but they appear to have no effect.
I've reinstalled Ultra, after having deleted the whole folder and downloading it all again, and the same behaviour persists. Has anybody else seen something like this? Or have I just done something wrong?
