Hi All - I've been sent an iok which is 21mb in size. I worked out it was because a .bmp file was being used as the background image for each tab and that it was 50mb in size. I set all tab background images to 'none' and then went to Style/Background Image/Remove unused items from this list.This didn't remove the image from the iok file. I deleted all tabs and then selected that option and it worked but obviously Ihad to delete all the tabs. I'm not sure if this is a bug or not but is there a way to access all images associated with the iok and delete them? I really need to delete this image so i can reduce the iok file size. Cheers - Tim
