Quizzing - feedback layer background
In SL1 I created Multiple choice question using preset template. I modified the Correct and Try again layer (deleted the feedback, replaced it with green/red square). SWF export works fine - but HTML5 - I get greyish background overlay (see attached image - I adjusted contrast so that the problem is more visible).
I then created a new slide (2), added a button that shows the layer - and the above mentioned overlay is not visible.
Went back to slide 1 - added same button (to show a layer) - but the overlay is visible.
Tried importing SL1 scene into SL2 - same problem. Tried re-creating from scratch in SL2 - same problem.
