RC,
not sure about the force closing when switching windows, it doesn't
happen to mine.
I'm working on bookmark organization, it will be another few weeks, as
I have to rush out a release for cupcake first, thanks to Google and T-
Mo.
Yes, 37M is too large. Go to the home screen. Start Steel. Go to
settings, and press the "clear cache" and "clear history" buttons.
Don't leave the browser yet. Wait about a minute. Now press the back
button several times until you get the exit dialog. Exit the app. Use
some other app for like 2 minutes, ideally something that consumes
lots of resources, like maps. After a while, Android will finally make
the decision to kill Steel.
Now you can go and check in Settings->Application Management to see if
the size of Steel has come down.
The next release will fix the clear cache on exit bug, so you can have
Steel not use as much memory.
