Recently, the Wiggle tool has been getting stuck.
For example:
Some of the time (more frequently than in the past), the protein will not move at all.
Workaround: Nudging the protein first and then wiggling will solve the problem in most cases.
is this in the latest update to "main" or in the most recent "devprev" update?
It is in main.
not at all a recent problem. Also particularly common after using strength 10 bands. After removing the bands, it just sits there. You have to manually nudge the protein with the pull tool, or a low CI shake, or (very) low CI wiggle. See for example http://fold.it/portal/node/992533 . It's not puzzle specific, it happens quite commonly.
Right, it is not a recent problem, but the frequency of the problem has increased dramatically.
