Default loaded programme on startup

My problem and question...

Every time I open Primavera (6.1) and log-on, it defaults to load a programme that I haven’t used in 6 months. It also defaults to a layout view of that programme which I had used on other programmes, which has filters set that bear no resemblance to the currently loaded programme, so the result is the screen is blank, as the filter is filtering on some codes that the programme does not contain. It is easy to just load the programme I want and then load the view that I want, but it is annoying me. I use v6.1 and it is stand alone version on my pc only.

What makes the software decide that on start-up, it will load a 6 month old programme with an irrelevant layout view? There must be a choice preference setting, I think.

Does anyone know if there are any settings where you can change what the default start-up programme should be? I have looked around but can not find it?
