I made a new version of the TransPutty update mentioned in my earlier blogs.
It was based on a 0.54 dev-snapshot, this new one however is based on the
0.56 release which is immune to some security exploits that are present in
0.54 and 0.56.
So if someone happens to be using the transputty executable it's a good idea
to get the newer .exe from my site at http://www.cs.helsinki.fi/u/mxkoskin/
... and yes it is a very crude pseudotransparency requiring an alternate
background image ('putty.bmp' in the same dir as transputty.exe) to work.
I suggest using a tinted version of your background that you can create
with your favourite image editor. (Gimp, photoshop etc.) Cheers.
