Sometimes when I click on a link that is supposed to open a PDF I will get a dialog that appears in the upper left part of my screen that is blank except for a ? mark. This dialog has an "OK" and that is it.
I am on the latest version of 9.. any thoughts?
As an update the work around is to have Adobe open in the background and you wont get the error.
The software in question calls the registry to launch adobe calling HKEY_CLASSES_ROOT > .pdf > AcroExch.Document
