heres what im doing in the rb app:

-- code --

dim pid as integer
pid = fork(); --> plugin function pointing to "System.Frameowrk::fork()"
if pid < 0 then
// do error stuff
elseif pic = 0 then
// do child stuff
else
// do parent stuff
end if

-- code --

if i remove the fork call, the app does not crash. Oh, BTW, its not the
rb app that is crashing, its the forked process. Im not sure whats
going on, anyone have any ideas? It was working earlier, and all of a
sudden, just stopped.
