When using the Find function to search for specific records the default size of the Find window can mislead the user to think there are no records to select from.

The default size of the Find window is too small for some of the field values to be displayed which can lead the user to think there are no records to search for.
Resize the Find window by pulling down on the bottom right corner which reveals a list of selectable records and the right-hand side scroll bar.
