Problems with balsa too

Balsa's IMAP support seems very sketchy. The FAQ says Balsa cannot automatically discover IMAP folders. I tried adding a "IMAP folders" account instead of "regular" IMAP account with a folder name. I did get a list of folders but the UI just hung when I clicked on a folder. Looking at the strace it appears that balsa is downloading the entire folder without responding to the UI. Not good :-(. I am sticking to sylpheed-gtk2 for now.
