For some reasons DoorCS always reminded me Windows. Not only the look but because of what Tribal says. This sucks because the software is pretty good if you like lot of features. There's also that cool feature that instantly go to the program line in BASIC programs instead of scrolling from the top to the appropriate line, which saves BASIC programmers a whole lot of time. Idk if it still has bugs though. Apparently it had some rare crashes in previous versions.
