This is not unique to Microsoft Access, but that was the most recent program to piss me off: Have a scrollable text field in a form which is itself scrollable between entries. Place the cursor in the text field while the form is editable and there is text going down out of the visible area of the field.
Now try and scroll with the mouse-wheel.
The entire form will scroll or, if you're in some sections of Outlook, nothing will happen. No matter where the focus is, you cannot scroll where you want to, with the mouse-wheel.
This, to me, is either bad design or shoddy checking.
