Ian,
The correct code to add the flash is:
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="280" height="220" xcodebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab">
<param name="Movie" value="/uploads/clock.swf" />
<param name="Quality" value="high" />
<param name="wmode" value="transparent" /><embed src="http://cutesoft.net/uploads/clock.swf" width="280" height="220" quality="high" wmode="transparent" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" ></embed>
</object>
If you don't agree, you can create a custom dialog which insert your own flash code.
