Just installed OO 4.1.2. I opened a blank Calc document and went to Tools -> Macros -> Organize Macros -> OpenOffice Basic. From the OpenOffice Basic Macros dialog I selected "Edit" on the "Main" macro in Module1. I can add new lines to the macro, but the IDE crashes if I try to delete a line (pressing "backspace" from column 1 of a line).
I'm running Windows 7. This problem also occured on OO 4.1.1. I tried deleting my user profile but the problem persists. Thanks!
