I have experienced this problem twice in the past two days: When I
have a couple of applications open and I try to do something with the
appointment book, I get a message saying there is an internal error
and I must reboot. Things seem fine after a reboot however.
As far as I know I have about 224K free memory so that might not be
the problem. I also had the latest patched connectivity pack last time
I synced it a while ago.
What gives?
