FrameMaker 12 - shrinking files with graphic imports, can't see changes in shared files

I'm using FrameMaker12 on a new computer that was recently upgraded to Windows10. I'm having some strange things happening with the software (minimizing file size every time I click inside an anchored frame, co-worker can't see my changes and graphics are coming up grey boxes if someone else imports them even though the import is from a common folder on the same server). Is this a possible side effect of Windows10 or another issue? I can't find System Requirements for FrameMaker 12 on the Adobe website. Has anyone else had this problem with FrameMaker? This is a first for me.
