ok I went to the host list and did an edit to one of the hosts and gave it a group name, a new group, and did a save.
went to the group list and there it was, check the projects and everything was ok, so I added a 2nd and 3rd host to that group, did a resync with bam, and all 3 were good. no problems.
host 1,2, and 3 were intel cpu, running linux with boinc 7.0.27 64 bit, ubuntu repository.
added host 4.
amd, windows 8 pro, boinc 7.0.38, had no projects attached to it, but was already attached to bam.
after adding host 4 to the group and resync'ing with bam. no projects showed up on the project tab. went back to bam and check the group and all the projects had been unchecked in the group. check the 1st, 3 hosts, which by that time had already resync'ed with bam, but after having added host 4, and they had no projects,

,
so, As I have been told many time: it's not a bug if I am the only one that sees it.

just keep a look out to see if you see the same. well I may be nuts anyway and seeing thing. or they need to change my med's
