Scott,
1.5 is running like a champ! Thanks! I've only noticed some minor issues like my Wsibar Advance 3 acts a little weird sometimes by closing programs on it's own. Also when I launch Teeter, it immediately minimizes it to the background and I have to pull it up from the WA3 tasks panel. I have noticed that my phone sometimes does not ring, but I get the voicemail notification afterwards, and I've also had a couple of random lockups here and there, but nothing crazy.
My Garmin Mobile XT locked within 15 seconds and has been running fine.
I'm not complaining, just reporting back as you asked.
Nate
