Hi,
Why do you not use transparent=true for the WMS layer? What's the difference
to alpha=true?

Hi,
I'd say it's slower than a normal user can cope, especially when zooming.
I have an OL (current SVN version) web site with a WMS base layer (tiled)
and a WMS alpha=true layer (not tiled). If I use IE6 and I try to zoom
(small click on the little + button), my navigator will freeze for some
random time between 3 and 60 seconds.
By freezing, I mean not refreshing the navigator window, not using CPU, just
doing nothing.
If I remove the alpha=true, then the website works like a champ appart from
the transparency being broken for my non-base layer.
Sorry, no public web site to show. But I attached a PNG returned for my
second layer (in attachement).
My current solution is not to use alpha=true at all. If you have to support
IE6, better switch to GIF and forget about alpha channels and the added
quality.
CU.
