Odd Mouse contextual issue

Hi,
Ever since 10.1.2 I am seeing a strange mouse contextual problem where the mouse gets locked in the 'right click' state. I dont see this issue with any other software, and it only happens working in FCP
It seems to happen almost all the time when I start using transitions. I use Movements>Slide transition often, and this is where I see the mouse almost all the time switch into this mode. Sometimes clicking in a different window in FCP fixes the issue, sometimes not and I need to shut down FCP and re start it. A few times I needed to reboot the system.
I Use the orbita mouse. I have several of them, and just swapped out the mouse for another one, and still seeing the problem.

Anyone else seeing this?
OS 10.9.4

Thanks

Hey Kurt,

Nope, not seeing any of this with my Wacom mouse and tablet. You might consider deleting your FCP X preferences.

Not happening on my Magic Trackpad, either.
