Looking forward to it. Deleting again.
Continue where I left off, is one of the primary reasons I use Opera.
(using a plenty fast system here btw.)

Just had to delete files again.
Is this getting any attention?

Just wanted to chime in, that I've been struggling with this for a long time as well. Actually using Opera 12 for the most part because of it.
The fix certainly helped those multi second waits between clicking something. Hoping it gets sorted out.

I rightclick a tab first and saves all tabs to a speeddial folder. Clear session files. Restart Opera and then click open all tabs on the speed dial.
