To start with, I am no computer wizard and have no idea if there is a log somewhere to look up.
I am using Windows 8.1 on my Toshiba laptop, native locale Swedish.
Every now and then (at least once every day) the program frezzes for five minutes,
window turns dim and header saying “program not responding” (but in swedish, of course).
As far as I can tell it is totally random, it can happen when syncing IMAP accounts, sending
mail, adding attachements etc.
About every second time the program crashes totally and the process have to be “killed”.
After restart, the client starts to repair damaged databases. Why ? I have no idea…
I have purchased the “Pro” license. Too bad about this problem, I may have to go back
to Thunderbird again (even tough I like eM a lot better…)
