Unable to Select Single Character
I'm unable to select single characters in Pages documents using my trackpad. I left-click w/one finger and select with the other, as I have always done and can do in this online editor. The character will show blue highlighting but as soon as I lift my left finger from the trackpad to type, the highlighting disappears. For a while, I thought it wasn't possible to replace a selection in a document with typing, as the typing would always be inserted next to the original characters. This feature works occasionally but doesn't work most of the time.
Using Pages 5.6.2 & El Capitan.
MacBook Pro (Retina, 13-inch, Late 2013), OS X El Capitan (10.11.6)
