Toolbar Problem in Adobe Animate CC

I have Animate CC (2017.5) and a few days ago I started experiencing problems with the toolbar.
If I click on any of the tabs outlined in red, as soon as I move my mouse down to access the sub-menu, it pops me over to one of the tabs in the green outlined part of the toolbar and opens up its sub-menu. The only way I can access the sub-menu from the red section is to use my arrow keys.
If I click on any of the tabs in the green outlined section, no problem.
Thanks in advance for any insight,
John
