[imp] IMP 3.2-RC3: Large folder issues

[Per Steinar Iversen]

When I open a large folder in IMP 3.2-RC3 (previous versions too) then the
listing often open at strange places. For example at "Page 4 of 352" or
something like that. Any way to make IMP always choose Page 1 for example?

I list the messages by arrival time in descending direction.

Of course it is always possible to click on the first page icon after 
opening any such folder.

IMP runs with the latest versions of Apache, PHP, PEAR etc. on a an 
updated version of RedHat 8.0. The IMAP server runs Cyrus imapd.

...

A bit more worrying: When these large folders are accessed from for
example konqueror 3.0.3 then IMP navigates without them without any
problems. From MSIE 6.0 SP1 under XP, this does not work, the view appears
to hang once the folder is entered. Somehow it seems that IMP handles
these browsers very differently.

The mailfolder I used for these test contains about 18-19k messages.
