Insert Time at the right end does not work

When the cursor is at the top right at the end of a file, it is not possible to add more time.
One has to move the cursor a tiny bit to the left, than it works.


No insert at the end


just 1 ms to the left


Insert ok.

This needs to be fixed.

Thanks, this will be fixed in patch 1.

Thx !!!
This will be so helpful for doing stuff here.
