Hi! I've just installed the ParticleIllusion 3.0 demo for windows and it seems very buggy to me.
What happens is that the work area next to the emitter preview has a large square in it which displays a frozen image of whatever is under the window (like another app or the desktop). When I drag the program window the square is joined by more squares that cover most of the window. When I let go it goes back to simply being a square in the middle of the work area.
Needless to say this makes it impossible for me to work with and evaluate the software. Is this a known issue? Clash with my graphics card perhaps? I've tried to search your forums and google for evidence of others having resolved this issue but came up empty. Hope you can shed some light on this issue.
