OK. I installed the changes so that they should work for the Windows build (I don't want to mangle the other builds at this stage). Please have a look at the three problems from my last post. Note: Problem (3) is reproducible only in the left of two side-by-side windows. Since this is the strangest bug maybe you could have a look. I'll repeat how to reproduce it. Load the tutorial, split the window via C-x 3. In the left window move point to the rightmost column of bidi text before line 121. Lean on your `next-line' key until you reach line 121 - here redisplay hangs. I can't reproduce this with any other line. martin
