I've seen this behavior also ( freezing while composing ) - although
i've not correlated it with switching folders nor have I noticed the
"Storing ..." string ( but I've not specifically watched for said string
when it happens ) -- NOTE:  composing just paused while typing in this
email -- status line text changed too quickly for me to determine what
it was stating.

It seems to be occurring around freeze/thaw of folders????
If you start composing a message and vary holding down random keys you
can see the input pause...
