I think it does have an option to allow things like ctrl-clicking (I seem to remember that I get by fine on my iMac which has a one button Apple Wireless Mouse, but I don't remember if I use ctrl-click or what), and it also respects any OS X driver functionality. So for instance, if you are using a scrolling Apple trackpad that supports two finger right-click (natively or via iScroll2) or a corner tap for right click (Sidetrack), that works inside the Windows session also.As a side note, I find that RDC works best if you have a 2 button mouse as well.
I would like to try Cord, but the site won't let me download it. Seems like their link is broken or something. Do you have an alternative link to where I can download it?Microsoft Remote Desktop Client is free (and also already on your computer in the Office folder, if you have Office for Mac).
CoRD is another free option. Some people swear by it, but I personally prefer MS's product.
Both work with any version of Windows that supports remote clients (I think with XP, XP Pro might be required; I primarily use it with Win2003TS).
