I have the same problem with the ViewSonic 1100. It is set to hibernate and
I use it in LONG meetings--all day and then some. It sometimes comes back
to life and works fine for awhile and then it hangs while I am using Journal
for note-taking. I save the journal file often now, because when it hangs
you loose the notes you just took!

M/S needs to fix this problem RIGHT NOW, but I don't see any patches coming
out that will correct the problem. I also have a Sierra Aircard 750
installed and it's application dies when the Tablet hibernates. This too is
annoying and so far a reboot is the only solution. Anybody from M/S
listening here? You are going to loose the market if you don't fix this
problem.
