i run windows vista.
i can't get my filters to appear under "filters".
i can find them when i click "computer" off the start menu.
computer>local disk>program files>gimp 2.0>lib>gimp>plug-ins
i don't know if these are relevant but
when i double click one of the filters i am familiar with it says "component not found" on the top of the box that pops up.
i noticed colorize was also under the "plugins". when i checked to see if it was there(in gimp) it was. it also worked.
