There have been problems reported with the bluetooth at all levels in this device I have posted at palm.com about a problem I have with my treo bluetooth headset where the bluetooth just turns off all by its self. I have not gotten any answer as of yet. At this point I just hope that Palm will release some kind of patch. I will continue to check every day for any changes. Others have posted here about the problem you are having with the "Pop up windows informing of bluetooth hardware problems" but I cant find the post. You can find additional information about bluetooth problems
HERE Hope this helps
