"Dialog Width" option not playing nice

I have the same problem. It was working at one point but is not any longer – please see here: http://www.chesschallengeindc.org. The modal window should be 600 x 370 but is always 100%. Please help.

Nope – I’m moving on to a different plugin. This one has worked great: Easy Modal by Wizard Internet Solutions. I’ve used it elsewhere and it’s great – in particular the support is great.
