Version: 3.5.9 (using 3.5.10, Debian Package 4:3.5.10.dfsg.1-0lenny1 (lenny/sid)) Compiler: Target: i486-linux-gnu OS: Linux (i686) release 2.6.26-1-686 currently, in the categories dialog, to tick a category you're lost if you fail to hit the check box. Good web forms don't make the check box sensitive only, but also the text associated with that box. So, I'd suggest to do the same for the categories' list. However, clicking the category once currently helpfully just selects the cat. -- Then, why not make a double-click make it ticked/unticked? Would be a nice feat and relieve us of pinpointing that small check box square.
