Does anyone know any free computer programs that lets you draw molecules and curly arrows for mechanisms?

ISISDraw.  It's not great, but it's free and will get the job done.  You'll draw a curved arrow, then 2-D rotate to get the start and end where you want them.

Like I said, not perfect, but you get what you pay for.

Chemsketch is also worth checking. It's very versatile and has also curly arrows drawing function in its repertoire (it takes a little practice to get them look the way you want though).

Thanks for the help on both the programs!
ISISDraw is a bit complicated, Chemsketch is a lot easier for me to understand. Just, I don't know how to make the curle arrows for the reaction mechanisms, could you help me out with a screenshot maybe? ^^;

Here you go, the relevant buttons are highlighted in red:

Click, hold down and twist, click, hold down and twist etc. When you are done, right-click and thats it.

If want simpler curly arrows, try the two buttons above the highlighted, this tip was for those more complex curly arrows.
