M-x ediff-regions-linewise, type RET twice to use *scratch* for both Ediff buffers (it doesn't matter which buffers are used). 3. Try to select a region with the mouse => Emacs beeps and announces the error "mouse-drag-track: The mark is not set now, so there is no region" This happens on any click of the mouse in the buffer. Nevertheless, it is possible to select a region by dragging the mouse with mouse-1 pressed. Subsequently, further mouse clicks do not raise an error any more. The bug also happens if I visit a file and call ediff-regions-linewise on it. If I comment out the line (ediff-activate-mark) in ediff-clone-buffer-for-region-comparison (in ediff-util.el), then eval that function, visit a file and call ediff-regions-linewise, then clicking with mouse-1 does not raise an error. I observe this bug since r101737, which fixed bug#7044. That bug prevented even trying step 3 in the above recipe, so I don't know if the fix introduced the mouse-drag-track bug or revealed it.
