I found a bug with both RC3 and RC4 releases. It's difficult to explain so I'll do an example:

1) Load PCGen with "Pathfinder RPF for Game Masters" sources
2) Create a new character (unnamed 1)
3) Create another character (unnamed 2)
4) Go to PG Sheet of either character (let's say unnamed 2)
7) Now switch character (go to unnamed 1)... PCGen get stucked!

It happens with monster, pregenerated characters, etc. and with different sources (I only us Pathfinder books tough).
