The Adobe colour theme panel does not work - it is persistently cut off to the right hand side, the panel can not be dragged to the right and fully opened up. It is unusable. It does not behave correctly when docked with another panel either.

Serious bug that has been around for ages, well over a year and not fixed.

Current version of illustrator on fully up to date windows 10 machine 64 bit.

Preferences have been cleared/re-set, as has cache. I've also reinstalled illustrator and get same behavior. I've also tried with general Ui font size setting, nothing helps.

I am well versed with the computer and have many many years experience on illustrator - it is not my settings, it is a bug. PLEASE fix.
