Do you have that sudden dragging feeling, or lack thereof? Try as you might, you just can't seem to move your rows around. Well not to worry, the answer is here! OmniOutliner 3.7.2 beta 1 to the rescue!
We made a change in 3.7.1 beta 1 to fix a potential hanger when handling certain mouse events. Unfortunately it caused a few people to be unable to drag rows anymore. Since we haven't been able to determine why this change has caused this, we figured it would be best to just remove that change for the time being. Nothing else has changed in this release so if you're not having any problems with 3.7.1, you can simply ignore the 3.7.2 release.
