I have found that I can reproduce at will the issue of no phone numbers appearing on the Home screen lookup.

If I soft reset my phone, and do a lookup on the home screen prior to goodlink starting, it returns no hits. Once GL has started it still returns no hits.

The ONLY way I could find to fix this was to soft reset, adn BEFORE I do ANYTHING on the treo 750 I had to start GL, wait till it fully started and then the lookup worked.
