Siebel Clients for Linux

Hello All, Does anyone know of a Siebel client for Linux, my current attempts at getting the thin client to work with IE under both Wine (25th Jul) and Crossover 4.2 have so far failed without even a spectacle. The thin client seems to use some ActiveX component which I had hoped Crossover would work around, and although it installs, whenever I try to access the sight it crashes. Whether this is the fault of the browser or Siebel I cannot be sure :) Many Thanks, Ben
