I received your file but I am not sure what you are inquiring about. I don't see any custom currencies for 121 or 135 so I am assuming you are using the default 121 and 135 information provided by Logbook Pro 126.96.36.199. When you click the 'Lookback' button on the Logbook Pro status bar, do you see the 121 and 135 flyout information? It is updated whenever you actually click that Lookback button, as well as the report 'should' be updated every time the 121 and 135 Status report is generated. If you are seeing otherwise, please let me know, and also verify you are using 188.8.131.52. The 121/135 reports are based off of your Duration column.
I re-read your support ticket and think I see the issue. First off, I highly recommend you reset your spreadsheet style layout by going into the Spreadsheet area, click the far left icon on the 2nd toolbar row 'Logbook Options' then click RESET from the popup menu. Realize you can customize the display by right-clicking in the spreadsheet area then going to the 'Configure Display...' area, which is also accessed in the Options...Flight Log area.
When viewing the Windows Style Log I see you have checkboxes for 121 and 135. Logbook Pro does not break time down via these checkboxes you created but counts all time flown towards these calculations. Therefore whenever you make a duration change, i.e. new flight, modified flight, the 121 and 135 status reports will reflect the new information instantly. The 121 and 135 features in 1.9.x are 'quick info' areas and not designed to break time down per flight, i.e. some flights/types count, some don't. This is something that will be improved in the next version.
Hope this sheds more light on the situation you are encountering.
