Small error I am seeing…

I am seeing an error in my “Query Monitor” plugin.

Here is an error that related to Keyboard Navigator (which still works FYI, just trying to crush all the errors).

Screenshot of error: http://honeytrek.com/si/16_03_22_08Af1.png

Thanks if anyone has any insight or can fix this error in the next release.

Thanks
Mike
