Why in the would would you reinvent the wheel? 3.x absolutely stinks because of this. There’s a reason why pretty much 99.99% of apps use the standard Windows Save-As dialog box. Your new one has LESS functionality than Windows 1.0’s Save-As dialog box in the mid-1980s. Why don’t you focus on creating PDFs and NOT reinventing the wheel. Seriously, there’s a reason square wheels never took off, they don’t work. Your custom dialog window should be totally removed from the product and never brought back.
