I was running into trouble with editing text paragraphs next to images that were floated left.
All of a sudden I could not access the text direcly - the cursor would just NOT appear in it - and would have to go into the Text Editor to adjust text, or reset the Image Style, do my adjustments and set it to FloatLeft again. All very cumbersome.
What turned out to be the problem (thank you so much Helpdesk!!!) was that somewhere in the topic one or two images were in the same <p></p> tag!!! Once I separated the image from the paragraph all was well again.
Thought I'd share this snippet of info.
