I do not know how to explain this error, but when I select some tco and move them, and the pointer touches the right edge of the song editor, the tco move to a very long distance. Here I show an image:

Look closely at the edge of the lower bar and the right edge of the song editor.
Note to self: Does this still happen with #4973 ?

I do not know exactly, I have not tried it or I know how I would do it.

I tested it in LMMS 1.2.0 rc8.
I also confirmed that similar error occurs if the mouse pointer touches the left edge as well.
For reference, I can't reproduce this on my build with #4973 included.

OK. Closing as fixed. Please reopen if you still can replicate the issue on the master branch.
