Adobe Reader X is a nightmare! There also is a known issue when a user tries to open up a .pdf attachment in Outlook 2010 it closes. I had to go to edit—>preferences—>security (enhanced) and then uncheck the enhanced security “feature.” then I added an ADM in group policies to keep that from reverting back to the default the next time adobe update goes through.
Odds are that the next adobe/IE update comes by it will reset it back to the original internet preferences setting; maybe not but usually yes.
Don't take that personnel, it is just that I am so darned computer illiterate. I can follow directions if lined out as step 1,2 and 3. Nothing else means anything.
I'm old, I don't want to learn anymore, but they force me.
