Minimize stretch (Ctrl V) in UV editing has no continues grab support
I noticed a similar issue with the Phase and Random boxes in the Rotation panel of particle settings, Continuous Grab doesn't work there.
Daniel, have got patch for you http://www.pasteall.org/25613/diff but note that we're on deep code freeze and it's not release stopper, so it can't be commited before release is made.
thx! yeah lets just wait a bit then :)
Commited to revision 41136. Thanks for the report, closing now.
