I unchecked Enable Protected Mode at Startup and now pdfs always open maximized. How to fix?

[Guest]

Was getting 523 errors when trying to open pdf's this morning and the solution I found online was:

Edit/Preferences/Security(Enhanced)/ uncheck Enable Protected Mode at startup

This worked in eliminating the 523 errors but now pdfs always open maximized no matter how I set preferences for Acrobat to remember last view...

Any suggestions or workaround to get around this problem...

Thanks for your help,

Don
