To Repro:
1. In iclone, make a new project. (clear scene)
2. Create a sphere primitive shape
3. Set some "move" transform keys on the sphere from the Modify window.
4. Launch Curve Editor
5. Try to select a position channel in the curve editor, like Position.PositionX (Mine will not let me left click mouse select an individual channel.)

I can however, select the individual channel by using the keyboard arrow up/down keys. (This is my only workaround right now.)

I have the same problem on avatar controls.

I can not use the menu: Select Plugins - Curve Editor - Convert to Curve data since it is grayed out.

The position channels are not locked.

There should be no need to do any sampling since I can see the curves, and can get to them through the arrow keys, I just can't left click select the channels directly. This seems like a bug to me, because every once in awhile, a left click will actually select a channel, but then I won't be able to do it again, or select another channel.

Using Iclone v7.71 and Curve Editor v1.31
