Thanks Jon. You are essentially confirming what was becoming evident with
Deltek - that there is no product development nor fixes for current issues,
particularly with MSP 2007. I ask a Risk+ tech support person about any
plans for collaborating with Microsoft and fixing the MSP 2007 compatibility
issue and he said "no". Our only near term solution appears to be to keep a
copy of MSP 2003 going.
