i just updated to FF 3.0.12 and it seems less sensitive (could just be perceived). the problem is pretty easy to replicate by dragging the page quickly and releasing. what i just thought of and i will test out, is that it may be related to releasing quickly when the cursor is on the edge of the swf or off of it, because the swf is only 2 pixels wider than the page spread. i'll check it out.
there's also an issue of when the focus is not on the swf, and you click a corner to flip, the animation isn't as fluid as normal. if you click to focus, then grab a corner to flip, the animation is normal quality. this is also in FF 3 with wmode=transparent. is there a set focus script?
similarly, this issue seems like it's related how the browser handles flash and specifically wmode... i checked the CPU usage and for interaction with megazine in FF3 when wmode=transparent it's in the high 40s and when wmode=opaque or commented out, it's still in the low 40s. IE and safari are in the 20s.
thank you again for Megazine, for your dedication on the forum and for the regular upgrades. awesome!
