I'll try it with no space @R2elk.The one place it happens very often is when someone is tagged. If you select the tag from the list, it automatically puts a space after the tag. I am not sure if putting the punctuation directly after the tag affects the tag or not @Sally PB .
Tagging that messes up punctuation irritates me too. Re-phrasing the sentence is a nuisance, leaving off the punctuation is wrong, and having punctuation after a space is also wrong.
