Hi Chris,
DoogiePIM Version 2.3.0.0
I noticed just today that if I have a document name that includes caps, then implement a search by using F9 (for that same name but type in all lowercase, doogie won't find the document. Even though I uncheck the option that says, "Case Sensitive"
For the search I click the tab "Search by Field", Then select Documents in "Search in" and Name in "Record Field".
