Re: Re: Starting from scratch... (try 3)

Thanks! By the time you sent that I'd already found a slightly more
cumbersome way of doing it (also with Lua scripting - no disrespect to
mzscript, but it's nice to have a proper scripting language now!),
which also pseudo-docked the label to the VWM. I like the onmousedown
and onmouseup approach, though. It's given me some ideas for how to
implement novel user interface elements with labels.
