Recently noticed (now running 2003030908 trunk on WinXP) that when I mark something spam manually, the spam flag is lost if I switch to another folder and back. For a short moment it's there, but then it's cleared. This happens on two different IMAP servers. One of them is UW, I don't know about the other one. For POP3 accounts it seems to work. Sorry if this is a duplicate, but the amount of spam bugs makes it a bit difficult to search.
Same problem in 1.3 branch. Makes spam filttering at least difficult.
this is a dup of a bug I own.
