Hi - I had a similar problem with "fork" a couple of months ago but it seems to have gone away (in Windows).
I have noticed other oddities with fork since then, like a forked process sends some of its input back to the the parent window and some verb definitions seem to disappear after I fork off a process but I haven't nailed down the circumstances under which this happens. My definition of "fork_jtask_" looks like this: 3 : 0 0 fork y : ph=. CreateProcess y if. x do. Wait ph;x end. CloseHandle ph empty'' ) Does that match yours?
