you mean if you have a panel with more than 1 tab you can't change the tab (with the mouse)?
I don't know if the 2017 version has finally fixed the Windows display scale issue, but maybe it hasn't. Check your display scale value, and try it at the default setting.
The issue is that if the monitor is scaled to some other amount the mouse clicks you're doing are not hitting the right part of the Animate interface.
[looks to me like it's been fixed.]
