First, I appreciate the help that you have tried to provide on behalf of Intel...
I have tried every display driver available for my HD4600... I've gone all the way back to basic VGA drivers and worked my way through the Intel provided AND Dell provided display drivers one at a time....
I've investigated every option in the BIOS... there is nothing applicable to this... The BIOS has been updated twice to version A02 and thence to A05...
Restore points aren't an option... as CC Desktop has NEVER worked properly in this system. the 3257 build allowed it to install and "work" for downloading apps... but the Home and Behance tabs still don't work right and are black. IF you are logged in.
IF you aren't logged in, you can see the login on the home tab... and if it loses your application status, you see the "add apps" and/or link to behance options. BUT if the CC Desktop database has records of any activity history, it blacks out the home tab.... (though the active links to more information ARE there, just hidden).
Bottom line... CC Desktop is the only app (of hundreds) on my machine that won't work properly... It is a 32-bit app, and I suspect that lazy coding by Adobe is the culprit.
Thanks for your help... I am not going to waste time doing Adobe's job by setting up a completely new system partition to do their troubleshooting work for them.
Thanks again....
