GUI gone, again

Here is another instance of CFP GUI not showing when clicking the tray icon. I am running WinXP SP2 on a Virtual Box together with AVG free AV and SpyBot SnD. Host uses KIS7. I have browsed this forum, there are some threads about this but no conclusive answer. All suggestions have been tried to no avail. So I suppose my question amounts to this: Are there any news about the issue or do I really have to ditch CFP?
