Ok Nick,
had the machine running on 5.5 for an hour or more and until now the problem did not resurface. Not sure what to make of all of this but I won't upgrade or go
back to 5.6. for now. I don't know if anyone else has encountered something similar. I just hope I don't have any issues with bugs in 5.5 that 5.6 was supposed to fix which would force me to reconsider this.
John
