I believe that this bug still exists, but may be a Outline plugin issue. When you are editing a cmd file with the Outline plugin running and there is a line with a long line that wraps like this:
If you up arrow from below the line, the cursor will stop at the first “=” character and not let you move the cursor above the line.
This should be fixed on 7.00.1 RCx. Which version of EmEditor are you using?
