1.6 for Windows "bugs" or "annoyances" I've found so far:

The new LimeWire for Windows is great, I appreciate the nice work. That said, I'll get straight to the point.

1) selecting an upload in uploads window is almost impossible.
2) downloading multiple enumerated files not allowed, because they are too similar in file names.
3) launcher looks for VM in C:\Program files\... when it is actually located elsewhere.
4) preferences window - Drop Messeges From These Hosts
Here's a problem that I encountered, let me explain what I did:
a) added IP address X to the "Drop Messeges From These Hosts" list, pressed OK.
b) later, added IP address Y by pressing the "add" button.
c) Y replaces X. Hmm, odd. I'll just press cancel and retry. I press cancel.
d) Preference window revisited - X is gone, Y is there.
I don't remember what X was, so, that's lost~!
