[Google-Desktop] it doesn't index all pst files contents, i'm giving up

there's nothing to do, unless someone helps me to solve such strange
issue.

I'm using GDS 20051208-en.

I have Outlook 2003 connected to an Exchange server with a delegate
(ie. actually two folders), a couple of IMAP accounts (ie. two IMAP
folders) and 5 pst archive files: there are around 20000 emails over
there.

the issue is GDS starts indexing but not all of the emails are then
available. it seems something stops it from batch indexing the whole
files; once I open an email it gets indexed, but even if I use TweakGDS
or ReIndex tools, I never reached indexing completion: sometimes I got
3000+ emails indexed, sometimes 2000+ or whatever.

my PST files had a (stored) password, I even tried by removing it, with
no luck (actually they don't have any password). I tried reinstalling
GDS, both with Outlook active (it asked to shutdown it) or unloaded.

something blocks it. why not to have a debug mode, an error log or
whatever helps to understand the issue?
