Here is a sample screen capture I did with Faststone Capture to show a bit of what it can do.
You can use boxes with colours of your choice with text inside to explain something on-screen. A bit like the balloon effect in cartoon strips in newspapers, with the boxed arrow pointing to the characters' mouth when he's talking.
I've also used a yellow highlighter box over some text to draw attention to it. Just like using a yellow highlighter pen on paper.
I'm sure George and Colin will see some similarities between this and the other two programs mentioned here. There may be other more advanced features in the other two programs I'm not aware of, but as George has said, it is worth considering at least one of these suggestions.
Screenshots can be very useful in showing a particular problem any of our members may have using George's software, and who want help solving the issue. Or indeed a screenshot of anything else members may find useful in explaining something to our members.
Re-iterating what George said - "A picture is worth a thousand words."
Please consider trying one of these programs. I know George will definitely appreciate it when you require his help to solve a problem.
Laurie.
