Nice to see you on the dev-list, Ben :-)
Yes, Ben is correct. Watchpoints are basically not supported on the device
right now. I agree that it would be an excellent idea to have watchpoint
support for the emulator, but I think there won't be too much disagreement
when I say that the stability problems are a higher priority on our list
right now i.e. the connectivity problems, etc. It's something on a possible
feature list for a future update.
