can't change themes anymore

[superflysocal]

so no one is having this problem?

can someone at least tell me where default themes are stored.

another thing, when I go to select themes, when i highlight windows default theme (my current theme that i can't get rid of), i noticed the beam and delete option is not lit up, but all the others are. I thought it might have meant that current slected themes cannot be deleted so i selected another theme and that theme still can be deleted.
