ISO's lock up when I soft power down. Any suggestions?

Hi all. Every time I soft power down (for example, in an airplane when they tell you to turn off electronic devices) my iso's lock up. Has anyone experienced this? What is the cause and solution? Thanks.

hm strange, but your other games work? the umds or movies or anything. I know you can still text when they tell you that because it uses digital technology or something.

Yes, my other stuff works (nesterj, mp3's... etc)

what firmware are you using?

3.52 M33-4.

Thanks for the help. I am very confused about this.

Is your umd-mode set to enabled, or disabled? Shouldnt matter, but i know sometimes settings can get a little glitchy.
