I've added the following to my Fluxbox menu to open a VNC connection to my Windows box but for it to work I have to have it open in a terminal window (so I can put in my password, etc.)

When I was using Gnome I could check a box when I added something to the menu that said "open in a terminal window."

How can I do this with my Fluxbox menu?
[exec] (VNC to Win) {vncviewer 192.168.1.134}

Or another way to put it - how do I run 'vncviewer 192.168.1.134' in a terminal and force it to open a new terminal? (although I think it does that by default.)

Thanks.

It would depend on your terminal, but normally you'd append the command as an argument to your console command. I use aterm, and the fluxbox menu item would be:

[exec] (VNC to Win) {aterm - e vncviewer 192.168.1.134}
