I'm on Windows 7.
The functionality to move windows to other desktops doesn't appear to work. I've tried it with the "Send Window to Desktop N" selection from the window menu, but that appears to do nothing. The window doesn't move to another desktop, nor does my
current desktop change.
The behavior of the hotkey for "Send Window to Desktop" is even stranger. Sometimes it appears to do nothing, sometimes I'm not sure what it did.
At some point while experimenting with this, I got some sort of error dialog from .NET that showed Finestra in the stack trace. Unfortunately because of how strangely Finestra was behaving, I couldn't save the information.
