I'm glad I'm not the only one. This is less than a gigantic issue,
but it's more than trivial. It's a frequent inconvenience, at least
for me, probably for some other users.

I don't know how to use the unix terminal, but I have a GUI utility
that tells me that stuff.
When idle, Rev uses up to 90% of my CPU, depending on the number and
size of the stacks open, and if any of the scripts periodically send
messages somewhere. If one small, simple stack is open, it approaches
0% usage. It shares the CPU nicely with other CPU-intensive apps, and
nothing seems to bog down simply because Rev is sharing the CPU.
Besides, this occurs when no other applications are running.
I have looked at my CPU and RAM usage utility during text-bog-down.
Nothing looks unusual, but I might have missed something.
Apparently this is not a rare phenomenon. Is it Macintosh only, or
does it happen on Windows or Linux machines, too?
Come to think of it, on many occasions, I've seen Rev text bog down
in a small, non-scrolling field, containing 20 characters or less.
No doubt, many of the list's tech savvy subscribers understand this
phenomenon. What's going on? Is there a preventive measure or a way
to make Rev behave without quitting Rev?
I just looked through Bugzilla. Searching for "text" produced a lot
of reports. I looked them over, but I don't see any recent ones that
resemble this issue. It's not necessarily a bug anyway, I guess. It
might be an unavoidable consequence of the way Rev works. I dunno.
