Thanks - but as I'm typically changing context with each step (from one
thread or function to another), adding and then removing items from the watch
window before each step isn't really very helpful - basically, it's just like
using quickwatch. Watching actual variable members - instead of calculated
"properties" - is another workaround. But, I'm fairly certain the hang I'm
seeing isn't just "slow response" - I've left it there for around 10 minutes!
It is almost certainly a deadlock of some sort. Can microsoft please respond
with a verification that this a true bug (and a fix would be great!), or else
provide some rationale that they don't think it is a true bug (and so tell me
what I am doing wrong)?
