Edit: After reviewing other comments, it appears people weren't aware that PuTTY has X11-style copy/pasting. It helps to read the docs, folks:

Aside from the various UI paradigms Microsoft has espoused over the years (eg. the 2003 sidebar, the 2007 ribbon, the 2010 tabbed ribbon), other vendors think they have their own intelligent concepts of how a UI should look.
It's just a damned good idea to RTFM, or at least skim it. I skimmed the PuTTY FAQ on day 1, many, many years ago.
Seems like if one couldn't figure out how to cut and paste in PuTTY, they'd check the docs.
"Last update: November 25th, 2007.
Please note: I have decided to stop development of the PuTTY Tray patch, and I have no plans to resume it at any point in the future."
I hope the Tray guys will release an update incorporating these 0.61 changes.
Also, I get complaints of my coworkers because I configure SecureCRT to behave like PuTTy, they say it's dangerous :-/
(I used to use Putty to check my email using mutt remotely when on vacation).
