Bug report - Zoom Settings
There is a bug in Adobe Acrobat Reader for Windows. If you go into Settings-->Page Display and try to select the Zoom level to 100% or any %, it gives an error "Please enter a value between 8.33% and 6400%" and the reason the error occurs is because Adobe has a space between the last digit and the % sign in their drop down selections. The space needs to be removed.

This happens on Mac version too! Entering the % manually without a space worked. Thank you so much!
