Indeed, that's why I asked if you had altered a desktop setting.

I'd have a look at the config file for your WM. The site for pekWM
seems to have good documentation but I haven't actually tried to work
with it so YMMV.
Verify your config , I know there is a fontstring attribute , might
this be your problem?

I have tried ice and flux, both work well once you get the config
right but it can be a pain to get everything just so, usually i just
sell out here and use GNOME or KDE :^)

Under Themes and Autoproperties you may find some enlightenment.

I'm obviously inclined to think its the window manager, maybe some odd
keyboard shortcut you inadvertently pressed? Its happened to me.
