Arbortext IsoView 7.3 doesnt display CGM files
I have Windows 7, IE 9, and some security settings which turn various things on and off in IE9 to make it more secure
Arbortext IsoView Control is Enabled in manage add-ons
I can view the majority of items in the WebCGM static-graphics (V1-3) tests, and the dynamic10 (V4) tests,
However, when I try the WebCGM 2.0 add-on test modules, each time the page loads, I see a 'PTC' image, instead of the CGM object.
Pressing F5 or Ctrl-F5 results in a different PTC image, and I simply cant get the CGM object to display
Same thing happens for the WebCGM 2.1 Test Suite
The PTC image that appears, for example, says "Arbortext IsoDraw Intelligent Graphics, PTC.COM", or "Arbotext IsoView Evaluation Copy, PTC.COM" and I simply cant get the 2.0 or 2.1 drawings to appear.
Any ideas as to what may be causing this?
