Do you use old font design applications alongside new ones? Even though I mainly use FontLab 8, I still rely on a 22 year-old version of ScanFont for autotracing textured type. And occasionally, I need FontLab Studio 5 to do some things FontLab 8 can't do. I use TransType which hasn't been updated in a decade for a quick family grouping check. Does anyone else still use old font applications now and then?
