Problems upgrading to latest Horde / IMP

[Rick Romero]

I'm having a very strange error, that almost appears to be a timeout 
problem..   (But I can't find that article again)
	
I started out with:
Apache 1.3.12
MySQL 3.22.26a
PHP3.0.16
Horde 1.0.11
IMP 2.0.11

I upgraded to allow for PHPWEBLOG to :
Apache 1.3.14
MYSQL 3.22.26a (no change)
PHP4.0.3pl1
Horde 1.2.3
IMP 2.2.3

After seeing that my old IMP didn't work in PHP4, I went to update 
it. Results:

Documentation doesn't really cover PHP4, so I winged it.  
	It appears not necessary to add extensions to php.ini, they 	
	appear to be compiled in.  If I add imap.so, I see an error in 	
	apache's log that it can't find the modules.  MAYBE this is my 
	problem, but the symptoms don't show this.
	
My test.php3 comes out fine, no errors.

I can goto hoard, goto IMP, login and see my INBOX.
At this point, If I do ANYTHING else, I'll be returned to the login 
screen.  But it doesn't appear to log me out.

If I get kicked out of the new IMP, and try to login from the old IMP, 
I'll be 'automatically' connected.  I've never logged out.

I've removed the /usr/local/lib/php directory, and reran make install 
to ensure I had no php3 stuff laying around.

I didn't copy any data from my old install, just made sure the info 
matched properly.

I've re-configured php.ini-dist as php.ini in /usr/local/lib, with the 
correct settings.

I fixed apache/php/prepend.php3 to have an absolute path for 		
	PHPLIB.

Everything says cool. I can actually do MORE in the old version.  If 
I click 'contacts'  I can see my one contact in the old imp, the new 
imp immediately closes the window that is opened.

No authentication?  My PHP session is not persistant?

Any suggestions?

Thanks!
