When I switch to dual mode the width of the sidebar drastically increases. I have MBP Retina and Mavericks, but it has been the same in ML.
Yes, this is really annoying. I will work on a fix soon-ish.
You fixed it, nice, thanks! It works great now.
I’m still having the same problem, and running the latest version. I’m running MBP late 2010 model. ??
I’m still having this too.
Well, some sidebar width change may be forced by small window size. If there is not enough room in left (or right) side of dual mode, Finder shrinks sidebar to minimal size allowed. Isn’t this your case?
Do you guys have some reproducible steps for me?
