When I open an ECU that either has an XML file or doesn't, the map edit window doesn't show after a while of using it on either my desktop or laptop, although I can open the functions window. A virgin install of a zip file I emailed to someone else that had ECUedit, xml and a ROM in it and worked on their machine and my work machine now doesn't seem to work on my desktop or laptop. A fresh install from the zip download into other directories also doesn't work.
What am I doing wrong? One day all the editing features appeared, now when a ROM is loaded it loads but doesn't allow any editing/map definition etc.
