Now that you mention it, ISTR noticing that Eudora development had stopped, and that I felt something like "unsurprising; they've realised it has gross failings". Or maybe it was just that Qualcomm(?!) decided they weren't interested in it.
It was purely a marketing thing. Qualcomm decided it was not a core business area and they didn't want to spend their time with it. Like a company I've done design work for, it is hard to get their attention if your project costs less than $100 million to develop. So a perfectly good $10 million project doesn't get done!
I don't use it for email, so there isn't much junk or trash. My problem with it is not that it goes away for minutes at a time, rather it goes away for 2 to 15 seconds every 2 to 10 minutes. Sometimes I can't get through typing a post without my typing locking up three or four times... I know, I know, type faster!
I don't see any system resources being used when this happens. It is something strictly within Thunderbird.
I will also say I'm not a fan of Mozilla support. It just doesn't seem to be very effective and the organization and search features on the web site are very sub-optimal. Very sad.
