Bug fixes, candidate for stable release.
If the double-fire of mouse clicks in worker mode is what's been causing the animation editor to open unexpectedly after SINGLE-clicking (or holding a click and much, much later releasing the button) over an object OR opening an event/action line edit box when doing something like moving an event/action to a new line...then THANK YOU!!! That has been annoying me for MONTHS!
Ah shucks. Maybe try using a different mouse? When some mouse buttons get worn down (or maybe the mouse is just a POS) they tend to double click when you mean to single click. That has happened to me with several cheap mice.
The fix was for the runtime, that's the only place worker mode applies. It doesn't affect the editor.
