I am using Act V20 on a windows 10 machine. Today I accidentally cleared an activity form the separate activity pop-up. I moved to the contact and erased the activity but at that moment the whole pop-up disappeared. and whatever tried I do not get it back nothing seems to work. Strangely enough, when I schedule a new activity for today the pop up appears again. but only with this new activity.. I suspected at first that I cleared all today's activities by accident but that does not seem the case. How do I get this pop-up back?
