Have you tried searching the Ti archives? Sorry, I got SLAMMED with work this past week and have not had the time to follow the slow-Ti550 thread as close as I wanted. Being a 550 owner though, I have been paying attention.. My memory is completely depleted right now and I am running off the scratch disk.. But I think I had the EXACT same problem as you a month or two back. I may have posted to another BB - I will go check that now. Basically though, I think I had that same problem and after 'killing' that item, it never popped up again. How often do you have iPulse updating?
