Heart rate data not getting captured intermitently for some activities

Do you mean it's not capturing heart rate at all throughout a run, failing to capture it at the beginning, or dropping out intermittently throughout the run?

When I upgraded to 4.60, it was taking FOREVER to initially lock onto my heart rate. Sometimes it would finally lock on a few minutes into the run, other times it wouldn't lock on at all. It seems to be getting better with the new beta builds available for download.

I have been using my garmin forerunner for last 6 months now for running (outdoors and on treadmill).
For the past few weeks I am observing that for some runs (both indoors and outdoors) the heart rate data is not getting captured.
its intermittent. I saw this start with the 4.60 upgrade.
I havent changed any settings since I setup the watch the day I bought it.

Has anyone seen something similar?

It seems that getting a HR lock is faster with the new beta releases (and maybe 4.7) but here is a little workaround that works for me every time. Before I start the activity, I first go the HR widget (down button once) and wait until the Heart icon stops blinking (takes < 30 seconds - HR is now locked). Then when I enter a Run activity, I have a HR immediately and throughout the run (you can see the Heart icon within the activity too). This seems to work for some and not others, so good luck I guess ... I figured this out when my HR was missing for the first 5-7 minutes of several runs shortly after a recent update (can't remember which one now).
