I clicked on PREVIEW POST and instead of the normal preview window I got the ad that tells you to click here to skip the ad.

Didn't seem to want to take the "click here" - that was getting no where - like it was a dead link...

But when I clicked the BACK button (which I was really afraid to do as I expected it to lose my post!) I arrived at the PREVIEW POST page.

That sure seems like what I did - but I'm only 90% sure of it...

At any rate - that is a pretty hard moment to navigate when all I was trying to do was PREVIEW a POST so I could SUBMIT it...
