XP SP3 2G RAM
Calibre was minimized overnight.
No Tray Icon.
No Fetch News.
Device not attached.
Task manages said 3976K and incrementing.
Maximized: Calibre jumped to high 7xxxK and is still incrementing 4K a step.
CPU% toggles from 00 to 01 occasional between steps.
AVG free is my A/V

Kovid. Is it possible to get a task logger to enable? Not the full debugger.
What the log would show would be user activity:
Minimize, Convert(single), Metaedit(single), Send to.., open Tag Browser, Tag select, Show Book Details,Fetch News (auto) count, Fetch News (manual)
That kind of thing.
Just while I have been writhing this (and nothin has been done with Calibre) it has incremented to 9132K
