Incorrect transparency redering on screen
When I open a document that has a drop shadow applied, the shadow papers misplaced and distorted. If I turn the drop shadow off and on again, it fixed the issue. Also if I open a document that has an Outer Glow applied, it appears too opaque and too large. It seems that if I apply an Outer Glow to to the Object effect , save and close the document and reopen, somehow an Outer Glow is also applied to the Text effect. Other similar issues as well.
