Client issues

Having some calls come in after pushing some people to the post sp2 ftf
patch build 121595.

We have a dept where people have proxy access to 8-10 other users'
calendars and post things to them (appts, etc). After going to the
build 121595 client, when they post things in another calendar, the
client does not auto refresh. Symtom carries over even when going back
to the sp2 client build 120664.

Machines are win7 64bit. POA on sles11sp3 / oes11sp2, still running
gw2014 sp1.

Any suggestions?
