One of my students is having a problem with SW3D and refreshing the screen on Macs.
He has a SW3D sprite which takes up the whole stage. The user clicks on an object in the 3D world and is taken to a 2D screen. We are trying to just move the SW3D sprite outside the stage but still leave it in the score so that we don't have to reinitialise it. Apparently it works OK on the student's PC at home but it won't on the Macs in the University's computer lab or on my Mac.
The sprite moves off the stage alright (I tested its position using the Message window) but the screen doesn't seem to refresh. We can still only see the (now non-functioning) 3D image. I've tried setting the stageColor to the stageColor (as I've used in the past to get over QuickTime refresh problems) and setting (the stage).bgColor to itself and updateStage but to no avail.
I've found that if I make the stage bigger than the SW3D sprite, or even if I just stretch the stage window larger than the stage, it works ok in Authoring mode. But once I make a projector it doesn't work any more.
If we jump out of the 3D sprite altogether there is no refresh problem, but then we have to reinitalise the 3D sprite which takes time and takes us back to the initial view of the 3D sprite rather than where the viewer left off.
Can anybody please suggest any solutions.
Many thanks, John
