Irritating Main menu problem

Hi folks, I am very new to all this. So far have managed to run my DSTT with a 2G Sandisk with no real issues, but have one very irritating niggle.
When I switch on initially the game menu opens and I can chose any game from the list. However when I decide to save and try to go back to the game list - just can't get back to it. I have to switch off, then switch back on again! No big problem I know, but its very annoying. ???
Have I missed a download somewhere?
Can anyone help please?

You want to reboot back to the DSTT firmware? L+R+A+B+X+Y if I remember correctly.

Thanks - I tried that but unfortunately it did not work.
I'm not sure if the 'firmware' is what I was looking to find, so will try to explain a little clearer.
I have aprox 40 DS Roms on my 2G Sandisk card (all play without a hitch, thanks!) when I first turn the DS on the games menu loads and I can select whichever I chose to play. I cannot however return to that menu without switching the console off, then back on again and waiting for the menu to reload.
Again as I say, irritating but not the end of the world if that is the only way to select another game.

I completely understood.. Make sure you have Reset checked in your DSTT options. Remember, I used to have one.

Thanks for the advice, as stated I am very new to this - hence I now have to ask, how do I access my DSTT options?

Uh, if I remember correctly, there should be some sort of button you can touch on the bottom screen, just look for one.
