Yeah, it's probably not tested much on touch-based devices. Could be another behavior is needed there. And you second point sounds indeed like a bug. I've still got another listbox bug pretty high on my todo list, will check those together when I get to it. Just checked how VS handles it - and it has a second minmal selection line when mouse is still pressed while moving outside the listbox. Don't like it too much really, will probably either reset or apply (don't like adding more view states).
Merging r6803 through r6804 from branch releases/1.8 to trunk
Just some update as it's easy to lose overview when one report contains so many patches: 2-8, 10-12 and 15 are applied. 9 won't be applied (breaks deliberate default behaviour as selection should change while button is pressed and I can't reproduce a bug so far, so this will need another fix if there is a problem) 1, 13 and 14 stay open for now (and so will this patch report I guess).
More patches from my fork
Thanks for the patches, all looking good again! 5 (cmyk-ycck) was applied to trunk (changes behavior). All others applied to 1.8 (most already merged to trunk, last one should will be merged later today)
Bugfix: CGUITabControl can hide control buttons again when resizing element when it was scrolled already
