BB Messenger will deliver the message, it shows up in my inbox just fine until I get a ways into a conversation. Then it will show that there is a new comment on my Messages list, but won't show the new comment in BB Messenger. It doesn't do it all the time, just partway through a long conversation. I have to reset to show it to register, and then it deletes all of the previous conversation. Don't know if it's my BB, BB Messenger, Verizon, or a setting somewhere. Anyone else have something like this happen. It's rather annoying.

I will pull the battery from time-to-time.
You also have the option to reinstall the program which can be found at mobile.blackberry.com

Yeah, occasionally I'll do the ctrl-alt-del reset. It does resolve the issue. Sometimes I forget that it's going 24/7 and that it is a computer after all. My 8703 had some similar glitches that usually happened after charging. I guess I'll just have to remember to reset after charging, that should probably do it.
