Many thanks for your help. The paper is fresh but not kept in a fridge, it is kept with my mono papers which all keep OK. I have trapped out all the indicator lights but I do have a fair bit of glow strip dotted about - would that be the problem? The paper in question is Supra 111. I am having another colour sess on Saturday so was wondering if it would be safe to cut the stop bath out completely. In the various instruction blurbs stop bath use doesn't seem to get much of a mention.

All the best,
