Found out about Synfig a few weeks ago and have yet to try it out extensively!
I downloaded it yesterday and managed to get my tablet working in it.
The interface is a bit intimidating, but my lack of money and love for open source urges me to persevere!!
I hope to get the hang of it soon!
(and also, why does a command box appear when Synfig Studio is launched? I am anything but a programmer and running Windows 7)
