I've noticed an issue using MS Edge regarding the highlighting (or selection?) of text for copying & pasting - using either the mouse or shift+cursor keys - in particular that the browser has a real problem allowing 'reverse' highlighting - i.e. placing the cursor at the end of a portion of text and then trying to highlight the characters/words prior to it. 'Forward' highlighting works much better, but this is a problem I've not seen in IE, Firefox or even Chrome to the best of my knowledge.
@jdseymour1978 Hi! Thanks for reaching out! Can you explain the experience a little further? Does this issue occur on only specific websites? Is this something you encounter when using MS Edge to view a PDF document? Does it consistently reproduce or is it an intermittent issue?
