Q link sliders behaving wierdly

I've only notice this with JJ OS (I've not used Q link much on the akai one so I don't know if the same thing happens there).

What happen is the value of the q link sliders seem jump around, at first I thought it was a dodgy slider but then I noticed both of them do it.

I first noticed it when altering the length of events in the Midi grid edit and thought is was a bug in the grid edit because Q1 seems fine when adjusting levels in the mixer, however I was just messing about with the real time pitch shift and noticed it there too, here's what happen to the pitch value as I move the Q1 slider up on the real time pitch shift....

+0.0
+0.9
+0.8
+0.7
+0.6
+1.5
+1.4
+1.3
+1.2
+2.1
+2.0
+2.9
+2.8
+3.7
+3.6
+3.5
+3.4
+3.3
+4.3
+4.2
+4.1
etc...

So it seems to take a big step up then little steps back then another big step up and so on....has anyone else had this, is it JJ specific? Should I post a bug report?

EDIT, I've just noticed the sliders also seem to function fine when adjusting start/end points in the trim screen, this leads me to believe that it's OS related rather than a problem with the sliders themselves.

Sorry to bump this, could someone please give this a quick try for me, I'd like to know if this problem is specific to my machine or not.

Thanks,
Tom
