Yep... and I nearly didn't answer because this stupid forum here constantly logs me out and refuses to return me back to where I was after logging in. This has successfully reduced my reply count to perhaps 10% of what it was when there was a good forum... Nothing gets me worked up as much as my daily dose of DNN!

Anyhow.. I persevered and found the post again.. so here are my notes on the issue:

This article:

And my choice of modes:

To the Object tag, add the following parameter:
<param name="wmode" value="opaque">

To the Embed tag, add the following attribute:
wmode="opaque"

Good luck
