Hi Colin
I have this on the To Do list to make this an option in Preferences in the next version.
Thus, in Bank Genie 5 and Bank Genie Pro 5, the setting in Preferences will determine the default when you start BS421 in Bank Genie.
Meanwhile, the program does store your setting for the duration of each session.
If you set it narrow once, that setting will persist until you exit Bank Genie.
You can use other programs and return to Transaction Analyser and the last setting will apply.
When you restart Bank Genie (in BG4 and BG Pro 4) the setting is initiated to the default - which is Wide Columns CHECKED.
