Switched to new board software!
Could you check whether restarting your computer helps?
Just want to add that the context menu options do work if you run rightload as administrator and THEN check off the option in advanced settings. Also working in windows 7 x64.
Windows 7 Home Premium 64 bit here. I also cannot get the context menu to show up. I have tried rebooting and the administrator fix suggested above. That's too bad because this looks like a very useful tool!
