I am using the 3.2.0beta2 from CVS. I just did a update this morning and a fresh build, so I'm pretty much up to speed with the bleeding edge on the 3.2 series. Are you basically saying that 3.0.4 has additional code/fixes that 3.2.0beta2 does not?
I will try the 3.0.4 version tomorrow and report back. Thanks for the help.
