- the process window is not shown by default (this avoids having to flush an

+ will be shown even if the child process IO is redirected. Neither of these
+ flags affect non-console Windows applications or does anything under the
+ other systems.
Under Unix the flag @c wxEXEC_MAKE_GROUP_LEADER may be used to ensure that

needed). Calling wxKill() passing wxKILL_CHILDREN will kill this process as
well as all of its children (except those which have started their own
