I'm using "The GIMP for Linux & Unix" to figure out how to set up an animated GIF. Everything works except for #33 on P.280 -- setting a frame relay speed that is different from the default 100 milliseconds. I can't get my GIF to run at anything except 100ms. I'm using GIMP v.1.2.1. Can you tell me if there's an update in the way v.1.2.1 enables me to slow down my frame relay rate?
