But it seems that Bernd also has a patch from late last year which fixes that issue. (It appears to me that Bernd's patch is on the trunk, but I haven't checked to see what branches Bernd's patch might be on.) > > Is Bernd's patch insufficient to fix the 3.81 issues that you're seeing? I've just tested it, and it's sufficient. The reason why I posted that patch, is because I was not aware of Bernd's patch. Thanks, - Tom
