Hello,
I have found a bug wherein all the navigation features for a window are disabled. Skim 1.4.20 (94) on Mac OS X 10.11.5.
Here is how I am able to reproduce the bug:
When the auto update of the PDF is made, I can no longer zoom out, and the only way I have found to resolve this is by closing the window and reopening the PDF file.
Best,
JL
I cannot reproduce this, for me it all works fine.
