I have been using Composer (2015 SP0) for a few years without trouble and recently went to FILE>DEFAULT DOCUMENT PROPERTIES>VIEWPORTS to set a custom camera angle to be consistent with other drawings and the CUSTOM CAMERA VIEW fields are missing.
I recently transferred the licence from a PC running Windows 7 to one running Windows 10 Home. I tried repairing the install to no avail. Could Windows 10 be my problem?
On another issue, Composer is running s l o w. Could this also be related to the issue above?
PC is DELL XPS 15 9550 (16GB RAM 2.6GHz processor).
Thanks very much.
