Opening insert effects issue.

Cubase version 9.0.1.
Operating system MacOS 10.12.1.

In a normal situation when you want to open a insert that is inserted on to a track you click on the “E” logo
to open the edit window.
The issue is that now i have keep clicking a few time on the “E” logo to get the edit window open.
What now happens on the first few clicks is that the insert bar turns orange.
The insert bar normally only turns orange when you hold the left mouse button while hovering above the insert bar.
This issue only occurs in the mix console and the mix console in the lower zone.
The place where it doesn’t happen is on the channel settings window.

Please fix this.
