Using the text boxes on Chrome (I use Version 66.0.3359.117 (Official Build) (64-bit)) has some problems around the formatting sytles that have dropdowns to select your format.
E.g. the Text syle, Text size %, Text colour and Text highlight.
The dropdowns jump/flicker making it hard to select the format you want, the Text% drop down doesn't let you scroll because of this issue.
It works in IE which is fine for now so I can keep creating content but would be better if ity worked in Chrome as I use this browser primarily.
