A couple points here:
First, here is a zip of a clean DW/configuration/Shared/Spry
folder.
http://www.dbooth.net/spry/DWConfigSpry.zip
You can use it to get the blue outlines back.
Second, there is an extension I made for updating your Spry
files:
http://www.dbooth.net/spry/spry_1.5.mxp
Third: We will have a new extension for updating Spry files
available when Spry 1.6 comes out, in a few weeks.
It will update the files for the existing features in DW CS3.
It will not add new features.
Let me talk about that for a second.
There are legal/accounting rules that say something to the
effect of:
"You cannot charge for a feature that was previously free."
That means that although it is possible for Adobe to build in
support for new widgets into DW CS3, once we give them away as an
extension, we can no longer build them into the next version,
because you would have to pay to get them and that would break the
rules.
So we can build it and give it away, but it must remain free.
That being said, it takes a really long time to properly build in a
widget into DW and there isn't a big chance that new widgets will
be added mid-cycle. But don't think that we aren't looking at ways
to improve this situation.
So, that doesn't mean that some extension developer can't
make more widgets work in DW. We would love to see it.
Hope this helps,
Don
