Hi DjZaNIX, OK sorry I didn’t realize that!
I think in that case the issue is that Adobe Flash has entered a funny state. I suggest saving your work, closing down your web browser completely and then reloading your work from History. This will restart Flash and should resolve the issue.
It’s worth noting that the Pro Editor tools are run by Pixlr, who have no affiliation with Ribbet and so fixing specific issues within these tools is outside of our control.
