Rick,
In my previous email I should have finished my last sentence better than I did. My complaint was about the Windows dialog boxes covering the computer screen just when you don't want them to. Like being momentarily blinded when you are driving a car.
Like the example above, it seems that the Windows interface imposes limitations for CAD programmers and users alike. And it was wishful thinking that maybe a Linux or Mac version of IronCAD would have less of these problems.
And if there was a Mac version of IronCAD I would dump this Winbox in a minute!
