I know dualscreen isnt supported yet, but i understood that it should show kind-of-work on a dualscreen, except that it only works on the primary monitor.
I just want to let you know that on my vista x64 with dual-monitors, it behaves a bit more quirky...
Only my left (primary) monitor blacks out, but instead of showing the picture fullscreen, it compresses the picture into a +/- 100px high bar. that bar seems to be center-aligned over both monitors.
If this is already a know issue, then nevermind. :-)
Keep up the good work! it seems to have more potential/entertainment-value than babysmash
