Adobe has released a new Flash player v. 10.1.
This version is reported to have some performance improvements. This means that there may be some improvements for how the Flash drawing tool and DrawChat perform for some users. Usually these types of improvements are minor but every little improvement does help when you're creating a drawing with thousands of strokes or lines in it.
I would recommend that you update your Flash player to take advantage of this update.
IMPORTANT: it is highly likely that any quicksaves that you had in the Flash drawing tool will be deleted if you update the Flash player so be sure those are all saved as RMD files on your computer of finish and save them to the website.
