I have recently upgraded to Yosemite 10.10.3.
I have noticed that since then, I cannot preview any of my files using the spacebar. The preview does not shows automatically either, I just get the spinning wheel. Previewing works with files when not using TotalFinder.
I have tried upgrading to the 1.6.18 version but it did not fix anything.
Any idea as to how I can fix that?
