I was actually struggling with the same problem while modifying the graphics dialog. LyXLength could be augmented with a private member "bool empty", that is only TRUE in case of an empty-string input field. In stead of testing "if (len.zero())", we should then test "if (len.empty())". The len.zero() is obsolete and the value zero should be treated just as any other value. Cheers, Rob.
