smplayer-portable-0.8.5.5487-x64 in Vista x64. Along w/ my other post about it looping at the end of some vids, I noticed on quite a few vids, if I click farther along the seek bar or drag, it may jump WAY ahead. Sometimes 10 - 20 min or more. Definitely reproducible.
Same vids in other SMP versions don't do this, nor does it occur in other players, for same vids.
I checked settings in an older SMP version against this one - seem to be same. I tried at least 4 files, that at certain points would jump ahead of EITHER where I clicked on seek bar, or dragged the button & released. Sometimes it jumps back & forth a bit, from the seek release point, then finds a place to land. Sometimes jumps way ahead.
Seek options selected in all SMP versions:
Seek to position while dragging
Absolute seeking
Precise seeking
These settings have worked well in all past versions. Don't know if it's a setting issue or another that came up in r5487.
