h2core and h2gurellia dont work for me on my vista computer but they do work on my xp computer. On my vista computer the program comes up when i go to file open the program freezes!!
Would anyone know why this is and how to fix it?

Right click on the .exe. Then go to the compatibility tab. There should be a check box that is checked that says something like "Desktop Composition". Uncheck that box. Then open the program and it should work.
