Newbie: blank main panel after login in (on Solaris8)

Just installed Wildfire on a Solaris8 box and SPARK on WinXP box and same Solaris8 box where Wildfire runs.

SPARK connects to server from WinXP box w/o problems and I’'m able to see lower panel.

SPARK connects to server from same Solaris8 box as the server, able to login, but on opening main view, the bottom panel is blank.

Any suggestions? Thanks for the help!
