Confirmed on XP with Fx4 beta 10 and Flash 10.1.102.64

I do not experience this bug on Linux.

This regression is likely to break a lot of sites, setting to major.

Jim, can you look into this, or does this seem more like bug for roc or bas? Feel free to reassign.

This is a windowless control with alpha. I'd bet the work in bug 626602 will address this.

Would it be alright to dupe this over to get it out of the blocker lists?

I think so.
