dilettante.... You read my post before I updated it. I removed that statement when I re-read it an saw it was false.

Regarding safer subclassing... Probably regarding some free, outside DLL (name escapes me) that was touted as the next best thing for safe subclassing within IDE. Never really caught on I guess.

Points I was really attempting to make in my 2 replies above was that: Want to subclass something? Put the subclass procedure in a module. That does make subclassing unstable in IDE. Want to add thunks or something else to make subclassing safer in IDE? Fine in limited scope, but recommend moving to traditional subclassing before compiling.
