Comment 22 for bug 849624

when I run a trunk TB with a start page, e.g., thunderbird about:blank, it actually fails to bring up any UI, so in that sense, it does suppress the biff :-)

do you mean start folder uri? that's the folder we try to load at startup, and yes, that does prevent the selection of the inbox.

If you've configured Thunderbird to select the inbox on startup, and download new messages, I'd think you might still want it to download new messages on startup, even if you launched it with the -calendar option.

I don't really know how your mail/calendar widget works internally. Why does selecting the start folder mess that widget up and prevent the calendar view from getting displayed? You could do something like listen for the onFolderLoaded notification, on startup, and switch to the calendar view after you receive that notification. Or are you simply trying to prevent Thunderbird from downloading new mail on startup?
