	Would you perhaps be on a Novell network?  I found that early
versions (pre 2.15) had a serious bug in ANET3's handling of the DOS
EXEC ($4B) call which caused EXACTLY this behavior.  I fixed it by
adding the NOVELL flag in estruct.h and linking in a bit of machine code
(in execpr.asm) which saved and restored the stack pointer around the
call. If your environment is different, I would still try this as you
may have an unusual version of DOS or a TSR interfering with the EXEC
call.
