Worked: 2.63
Short description of error
On mouse release (after curve adjust), cursor jumps (or appears) back on place of initial click in RGB Curve node.

Exact steps for others to reproduce the error
I don't have all versions of blender now so I can't say when exactly this behavior occurred, but possibly with cycles RGB node.
2.63 and older versions works OK (this version of cycles is without RGB Curve node), 2.68 is first one I have on computer that works with this issue.
I use tablet, but I don't have a pen on it :)
I tried to disconnect tablet … the same behavior.
If you need some more info I can post I'm one big ear. Thank you

Hi, this is strange behavior. some questions.
https://dl.dropboxusercontent.com/u/55113627/%3E%20Blender/test-RGBCurvesNode.mov
(iMac 27" OS X Yosemitte 10.10.3 ATI Radeon HD 5750 1024 MB and iMac 24" OS X 10.8.5 ATI Radeon HD 2600 Pro 256 MB)
Now noticed one more think (see video) when I move slider, then on mouse release pointer appears on first click position - as with curve manipulation, and in this case it looks helpful - we don't have to move back pointer into slider area, and that is why I didn't post it earlier as a bug.
But small problem here is - if I click again (to move slider) without any mouse pointer movement, than node jumps :) If I move (even a bit) mouse pointer it doesn't happen. https://dl.dropboxusercontent.com/u/55113627/%3E%20Blender/test-Slider.mov
Here is a behavior in 2.63 for reference. Pointer stay at a point of release (curve or slider).
https://dl.dropboxusercontent.com/u/55113627/%3E%20Blender/test-263.mov
Somethink that maybe helps identify error:
I use Screenflow for recording, in this app I can activate "Click effect" on mouse click.
In videos you can see - click effect is not there for clicks with mentioned issues, but visible in test in 2.63 where it works. So also this app see differences with mouse click to move node and move curve.

So far seems nobody cant reproduce..
@ThomasDinges, @MartijnBerger: do you mind trying your luck reproducing the issue?
Nobody with OS X can't reproduce this?
My wife notebook MacBook Pro, OS X Yosemite 10.10.2, Intel HD Graphics 4000 1024 MB.
It is the fourth Mac with this issue.
I can reproduce on macbook pro with iris pro.

Changed to unconfirmed state, we are sorry, but we have to be able to reproduce an issue to investigate it. If no dev can do so within two weeks, we’ll have to close the report…
@mont29, thought @MartijnBerger managed to reproduce the issue?
Arg! sorry, read 'can’t' instead of 'can' :(
@MartijnBerger, do you mind looking into fixing the issue?

This option is broken on Macs since the beginning. Mouse warping or hiding is against the Apple UI guidelines, which is why it works so bad I guess.
How did the OSX team here accept it? Easy to see how broken it is:
I'm in agreement with OS X guidelines, and against manipulating mouse positions. Nice for some people, but then only behind a user pref.
Why is it bad? It kills muscle memory, it makes you lift up the mouse all the time to put it back. So in the end you don't even win anything (as in speed of use).
I can see why some like it though, especially if you navigate around with a mouse-lift habit.
@Ton,
EDIT, well actually it might be wrapping when shift is holded down. Not sure if any wrapping happens without shift tho.
Sergey: in contrary. It wraps the mouse in this case too (and it fails to).
Sorry, seems like my english skills are not enough to clearly understand the discussion now, so only one note to ton's post "This option is broken on Macs since the beginning." - as mentioned in the bug description - it worked well in 2.63 and older versions on Mac.

@FilipMond, this is maybe caused by the default activated
Continuous Grab
and the Update in 2.66 (see Release Notes). You can deactivate it in the preferences (Input Tab)Removed subscriber: @Leon95

@Leon95: Thank you. You are right, disabled "Continuous Grab" keeps cursor behaviour OK.
But "Continuous Grab" is super useful thing ... any chance to find solution?
Added subscriber: @Blendify
If its because of continuous then it is known todo any reason we are keeping this open as a bug a not a to do?
@Blendify, this is not the same as continuous grab issue, even when continuous grab is working properly (for view-port operations) this glitch still happens.

Fixed both the original reported issues with curves and the button focus issue explained by Ton.
The main issue is that contrary to what the comment in the code said, the cursor position must be set again when continuous grab ends, the same as on other platforms. Most of the changes are fixing some inconsistencies in coordinate space conversion to make that work.
I know it is not a chat here, but I have to say ... Thank you million times for this fix :)
