there seems to be a bug in Seg3D 2.1.3 concerning the paint brush. To paint a region, a left-mouse-click-and-hold and dragging should be performed. Releasing the mouse button should disable the brush. However, this does not seem to work - a single click and the brush is painting, even without hold-and-drag. 

Furthermore, paint strokes cannot be undone - they don't appear in the undo menu. 

Those two issues do not occur in Seg3D 2.1.1, to which I reverted now.

I am using a Mid-2011 27-inch iMac with 3.4GHz Intel Core i7 quad-core, 12GB of DDR3-RAM and a AMD Radeon HD 6970M 1024 MB graphics card, with OS X 10.7.2. Seg3D is compiled from source.
