Definitely non-standard, I've never seen this in any version of Rev. Do 
you have a custom mouse driver? System settings? Extensions? Something 
about your setup is different.

You can set this in System Preferences/Appearance. Which version os OS X 
are you using? If it's an older version (one that didn't have that 
preference option,) and you've used Tinkertool on it, I wonder if that 
makes a difference. In fact, if it's too old, I'm not sure Rev will 
support it fully.

Well, each field or group property inspector has the settings, and if 
you're using an independent scrollbar (unattached to a field or group) 
then the scrolbar object itself has those settings in its property 
inspector. You'd need to change the settings on every scrolling object, 
but if you're seeing the behavior in the IDE, the settings aren't the 
problem. The IDE is already written to act as you'd expect. In fact, I 
can't think of any property settings that would allow you to restore 
"normalcy", because the default behavior is "normal", and it would take 
some fancy scripting to override it so that it responded only to 
double-clicks.

I'm pretty sure if your experience was common, the bug database would be 
full of reports. So we need to figure out what's different with your OS.
