Grozny: Well that's an excellent experiment if you got 2 Evos at the same time, so I would assume they should be identical. Please let me know if you come up with a solution.
I wonder if it has to do with different soft or hardware builds. Since I tried everything, including uninstalling, reinstalling, etc, I believe it is in the programming of handcent and was hoping they'd fix it.
I'm subscribed to this thread, so I'll be looking forward to seeing what you find out. Many replies have said "this is so easy to fix, disable notifications", and I'm sure for them it has worked. But it does NOT work for all.
