this is a common problem mike, some of the journo's who contirbute to the mag lurk around here so no doubt your cries will be heard.
I think the S&S staff hold back issues if something exciting is going on in the Astronomy/space sciences world aka the relaunch of the shuttle missions. I would not be supprised at all if this was the reason for the delay.
I how ever do agree that the frequency of publication is very disapointing considering that up untill a few years ago there seemed to be few problems.
Dave if you are out there, might be an idea to bring this problem up at the next editorial meeting
