Boeing yellow circles around the switches on the O/H

[siluch]

The overhead screen has started showing yellow circles around all the switches. This is new and so far ( although still looking) I can't find any reference to this in the manual.
Could someone point me in the right direction so I can switch off these circles as they obscure parts of the O/H.
Many thanks

Did you find the solution for this? Yesterday evening the same issue started at my site. I'm not aware of any changes I made.

Ah, for me this worked. ShowHotspots=Off in pmsystems.cfg
