Just installed the 8/11/06 update today and with windows 98 workstations we are having a problem with EVO. User can login to EVO and the shell comes up, but we you try to run any program, EVO hangs. There is an underlaying message box that says "A call to an OS function failed". DBA Classic works fine on these machines with the update. This doesn't seem to be a problem on any of our winxp workstations. Our setup is client/server, pervasive 2000i, novell 6.5 server, mix of win98 and winxp workstations.
