just so everyone knows, DLP2 works on both XP (x32) and Win7 (x64) for me.
GR - no probs. shoot me any Qs you have and i'll try to help.
konfusion - custom buttons - you can, but there are limits.
mediachance have a lot of help info at their site.
link for custom buttons.
i think you can simply create a button "image" - in photoshop, as psd file - then import it into DLP2.
