Not sure what from. Log tail included in pic. Pressing "get latest" doesn't clear it - in fact, doesn't seem to do anything...
If I right-click a sub and "cancel downloads" the count goes down by one - I have seven subscriptions so that suits. Here you see I've 'cancel downloads"ed on rec.arts.sf.science.
Nothing extra is added to the log when I do that.
Might be a regression to the old stuck downloads thing fixed a month or two ago?
