I'm sure there are other bugs that have been fixed that we still have.  I'll

Ah.  I grabbed the head and just noticed (not surprisingly) alot of 
updates/differences.  I'll take a look at this branch on Monday.  Planning 
on moving to a newer 2.4 version soon, so this is good to know.  Thanks for 
the info, should help us out alot.

Thanks again,
Josh
