Hi,
I found a minor inconvenience: when launching the game and then stopping it, my scrollbars disappear because their alpha is automatically set to zero. This is due to the panel setting "show scroll bars" set to "only if needed" (since I generate the content procedurally, the panel is empty when I leave the game testing mode). It's easy to work around the problem by setting the scrollbar on show "always" as long as you work on the UI. Still it had me confused for a few minutes, so i thought I could report it.
