I've sometimes been having trouble reading some of the diagrams and charts in the lessons but I discovered that if I set my text to a smaller size (click on 'view', then text or font size, then select a smaller size then the current setting) that it makes the diagrams and charts much clearer.

'I thought as though you'd like to know'.

...if you're referring to the diagrams and charts that I post, it's sort of a "Goldie Locks" compromise between TOO big and TOO small...bigger is easier to see, but "eats" lots of bandwidth and screen visibility, while smaller allows viewing of side-by-side images but at a cost of "tinyness."

...if you're NOT meaning MY stuff...ignore this.

Hello OTM, well I'll respond anyway since it's any diagrams, not just yours. I just stumbled onto the fact that selecting a smaller font cleared the diagrams without even changing the font size within...less band width because the text font is smaller? I have no idea but it makes all diagrams throughout site totally clear and sharp so it works for me ! Heading for my lesson in 'G' now.
