Latest version on Mac OS disables resizing the composition window header horizontally.
Update 3/21/20: This is confirmed due to MRC by removal of all extensions (I don't use many) and add one by one.
Thanks for your feedback.
I don't have any MacOS computer so it's difficult to reproduce it. I'll try to ask some friends, but it may take some time.
Do you have other addons installed ?
I remember that some other addons may generate that kind of problem.
Please keep me informed.
