Yes, I downloaded version 1.4 (three days ago, I think). I compiled IMAP with php, and the hack seemed to work just fine.
I don't get the same problem when using Opera, for example (and neither does the other user)--just IE6.
Stranger still, even with the hack deleted, the cache problem persists. It's because of the entirety of the series of events that I believe that the cache issue ties in with the email hack. Super-coincidences? Could be, I suppose; but the sequence of things suggests otherwise.
Thanks for taking the time to read, Erwin
