Main problem: (I am running PI SE on Mac OS = Leopard) when I right-click in the library window and choose "load library", I get a popup titled "Emitter Properties in Library: blah-blah.iel", but no library loading options. I've got all the libraries loaded into the correct folder, but I cannot seem to navigate to any other library than the one it wants to load by default. Also, if I right-click in the library window and choose "properties, nothing happens at all. Finally, I downloaded the SE for Mac update, but when I run it, I get a failure to launch error. YAHH! I love Particle Illusion but this is killing me. Any help??
