Hi Everybody ! Thanks for the various suggestions. I have tried Volumeslider works good, but how do you get it to finish with the slideshow ? Mutesound crashes with "FMOD couldn't initialize Directsound sound device" on my WIN98 PC. I'll try it tomorrow in the office on XP As to the solution with the ยด'BIG' button, sounds great and I'll try it out but its a bit too complicated for adding to the already completed 250 slide show. I guess I'll just wait for Igor to implement the sound on/off in the navi bar. Paul
