I would recommend Hot Fix R02.
If you are running 2003 w/ SP1 or 2003 R2 I would also recommend the following Microsoft hot fix for 20 second login delays if you experience delays.

So those of you who are running CPS4 in a production farm (I assume most)….what are the essential CTX hot fixes to install? I have looked at the ones available for download for CPS4 on Server '03, but I'm not sure if I should install all or just the roll-up. It appears that the roll-up negates some of the others. Please advise.
Thx,
M
