I noticed that the clicks in the CVS version of tuxpaint are sticky - meaning for example one click toggles the paintbrush mode and simply moving the mouse simulates click and drag - clicking again toggles the tool. I have been observing some kids using tuxpaint and this feature has earned the honor of the top annoyance. I just checked with the stable version of tuxpaint .. and this feature is not there. So wondering.. whether this feature was recently added ?  More importantly is there any way to disable is (config or code). Please let me know.. this feature is hampering the experience of the kids and I would like to remove it asap.

Thanks,
