Inititate (formerly Arrow Launcher) is a pretty cool launcher, but I think I found a problem with it
I noticed on my unlocked Treo 650 with firmware 01.15 that dialing directly on the keypad (physical buttons; not the onscreen keypad) would cause the call to go through but the UI would completely freeze – I could not go to speaker phone, hang up, or even turn off the phone. So I’d be stuck in the call, wasting minutes. This problem went away once I deleted Initiate.
Update 2005-05-04: I’ve narrowed the problem down to a single preference setting. I had removed Initiate last night as that remedied my freeze problem. Just now I added it back. No freeze problem. But then I went into the Preferences and enabled “Launch if letter Key held down” and that caused the freeze again. Unchecked it – no freeze. I’ve sent this info to the developer so that he can investigate further.
