@Ashley Thanks for taking your time to help me, it really is much appreciated! I completely forgot about the bound to layout behaviour so that helps heaps, but in relation to the .capx, as it is it actually doesn't work correctly. The bug can only be seen when you create a few instances of the object. Load the .capx and then click on the page about 10 times to create some instances. Then wait and watch. Eventually a few of the units will move off screen when they shouldn't. I read through the How Events Work sections carefully and it explains the way that events work in the way that I expected them to (edit: although by bad habit I use the explicit "for each" events on and off). Perhaps it is a bug?
Thanks for your help once again!valkyriegames2012-06-08 17:49:52
