[ka-Map-users] recent cvs updates

The keymap seems not to be draggable anymore. The transparency of the
legend is also off (intentionally?), but that's easily changed. Also,
did you remove all the zoom buttons (magnifying glasses)? Other than
that, most things seem to work ok in Firefox.

Unfortunately in IE, a lot of images don't appear. Prior to the
PNG-changes you made, they showed up as broken GIF's (same problem as in
Chameleon; images are valid, but show up broken in IE). With your PNG
changes, many show up blank (nothing), including the keymap (which
sometimes shows up after ten times loading). I know this is an IE
problem, so probably nothing much you can do about it. Unfortunately,
this problem is particularly pronounced from the server I'm running with
IE6 SP2, so I can't use Ka-Map internally for production yet.....
I just wish Microsoft could fix this.....
