Hmmm. I just checked again and as Roseanne Roseannadanna used to say, 'Never mind!' They all worked this time.

I run five projects and am receiving that message from all five. They are climatechange, milkyway, spinhenge, world community, and einstein. I tried rebooting, thinking that somehow it was a problem with my computer, but that didn't change anything.

It's been happening today only, except for world community which has never responded my efforts in that regard; it always stays at 100%.

I have not been able to change the 'project resource-share' on my several projects. 'We have encountered a problem communicating with your project' is the message I get. What's up? And, more important, what can I do about it?...
