Measure tool behavior changed?

Hi all,

I recently upgraded from 2015 to 2017 and now the measure tool is behaving differently.
I used to be able to keep the little measure tool window open, in the background so to speak, and still be able to access full functionality in SW by changing to the arrow/select tool.
Now in 2017, i have to close the measure tool window before I can go back to editing.
Even if I first change to the arrow/select tool.
To be more specific: In an assembly, if I right-click a part in the FeatureManager, I only get a small generic menu instead of the full menu that was there in SW 2015. If I close the measure tool, I get the full menu.

Please see attached screenshots for details.

Is this a change in functionality, a bug or is there a setting somewhere to get the old behavior back?

Regards,
Henrik

P.S. I had this behavior verified by my local SolidWorks support, but they could not provide an explanation.
