Hi,

While using system() to run external programs I noticed that
trying to run programs using DOS4GW (or any other non-djgpp extender)
resulted in the computer hanging.
Why is this? This doesn't happen with real-mode compilers -- I assume
it's a conflict between extenders.
This also happens the other way round; calling a djgpp program from
within a Watcom/DOS4GW program results in a crash also.

My question: how can this unpleasant behaviour be circumvented/avoided?

TIA
Elliott
