Upgrade for SpamPal to v1.11 is now available.
An upgrade to the Bayesian Filter Plug-in is also available. Please be advised, however, that following the upgrade I found that SpamPal crashed returning an Invalid Page Fault error message. Disabling the Bayesian filter resolved the problem.
I am running Win98 and Outlook Express, but my set-up is somewhat atypical due to customisation so other users may not encounter this problem.
