How to add a picture to your post.
A picture is worth a thousand words! (And yet I can' put them in the help file.)
Pictures really do help everyone solve problems so here is what to do:

Take screenshot of your issue (ALT-PrintScreen, open PAINT, then Ctrl-V) and save it as a file. Please crop the screenshot to only what you need. Windows built-in Paint Program works great for this.
At the BOTTOM of the post you are creating where it says New Attachment click the Choose File button and upload your screen shot. After it is uploaded put the cursor where you want the picture to be in the post and click the Insert TO Post button.
It will add text like this:
[attachment=2]
to your post. Note the picture will not show up until you actually Post. Not even in preview.
Note: Quick reply does not allow pictures.
