Hi! I've got the similar issue. The option 'Clip Output to Graphic Extent' has disappeared after some manipulations with Export dialog window size. I'm running ArcGIS for Desktop 10.4 under Windows 10 on a laptop with 1366*768 screen resolution. Any ideas? Thank you in advance! P.S. the problem gets solved when enable 'Auto-hide the taskbar' in Windows, but returns back on disabling this option...
