Fit is working as it should - you just need to rotate it 90 degrees by pressing the rotate left or right button twice (when its set at 45 step) to make it go around the curve of the patch. Set will allow you to do things like 2x3, 2x4, 1x2 e.t.c as fit is auto 1x1 If you want them going straight (in relation to the walls) then cap, as you already saw, works for that. As for save and compile issues, id be tempted to swap to radiant 1.6.4 (see downloads) or use a q3map2 frontend like q3map2tools (also on the download section) NB: The horizontal and vertical stretch arrows will increase/decrease the texture size from whatever you have set it to using fit/set/cap e.t.c
