Left Admin Menus Gone Wild!

The Problem I’m Trying To Fix: (Pics Coming If I CanUpload)
When using Chrome on my Mac and attempting to view the admin of any WordPress installation the Left Hand Admin Menu is displaying “funky” until a refresh is done – then it displays fine.

My Environment:
* Chrome (45.0.2454.85)
* Mac OSX 10.10.5
* Localhost via MAMP Pro (Paid) using Hosts via etc/hosts file
* WordPress 4.3

What I’ve Done:
* Uninstalled then Reinstalled Chrome.
* Emptied cache via Settings>Clear Browsing Data
* Emptied Cache via Click&Clean extension (doubt it’s any different)
* Cleared History
* Restarted Computer
* Restarted MAMP
* Checked in Safari – The menu displays fine.

Notes:
I’m pretty good in WordPress so it’s a bit baffling. It really seems like it is a version that is just stuck in the cache that won’t come out. I’ve looked at this in 5 installations and in all of them the menu is crazy. It doesn’t matter what theme, what plugins, how much memory, what time of day…lol. ////

All of the WP functionality is there – works great. It is just REALLY annoying to have this menu collapse on itself every time.

JUST REMEMBERED : On one of these installations I had tried a plugin to hide the top admin menu and that is about when this all started to go crazy. The plugin was installed on ONE installation of WP and then immediately deactivated once I saw it was not working as intended. Once it was deactivated it was deleted. I didn’t really think much of it until now – why would it be affecting so many installs though? Even from cache?

Thanks,
