Well, I'm not sure if I understand correctly but the block-copy information should be stored together with the copied text to the clipboard and not just be remembered by Scintilla. Imagine this situation: 1. User block-copies text in Geany (and Scintilla remembers it did a block copy) 2. User switches to another (non-Scintilla) application and copies some other text from it 3. User returns back to Geany and performs a paste. Scintilla remembers it did a block copy in (1) and will paste this text in the block mode even though the clipboard contains something else now
