Not really a technical issue but didn't know where to put this.. :P
In these Flossmanual screenshots: http://en.flossmanuals.net/PureData/Messages
which pd editing GUI is being used? It looks very nice.

Very different from the one on this page: http://en.flossmanuals.net/PureData/WirelessConnections
which is what mine looks like..

what do you mean? what does your pd gui look like? looks like the normal pd gui with a small standard pd main window on the left.

You mean grey colored boxes and stuff? I had this once, but I can't find it anymore. As far as I could remember it was an older version of one of the extended releases by Hans-Christoph Steiner, but it doesn't exist anymore -- or I can't find it. Give it a try if you want.

It most definitely still exists, in any Pd-extended version newer than 0.40.3

I might be remembering wrong but weren't the object and the message boxes also colored a little grey in the older versions?
