Comment 2 for bug 212183

I can confirm this, i wan on IRC last night asking about the same issue. Seems that it surfaced after a recent update, as this hasnt not happened over the past two weeks, just started yesterday. This was on my laptop. I tried using an external mouse to make sure there wasnt a problem with my touchpad buttons. I get the same results either way.

I did note that holding the right button longer brings the proper menu, but would definitely prefer the quick right click i'm used to.

This behavior seems isolated to Dolphin. RIght clicking inside other applications works just fine.
