I cannot reproduce the problem with `redir', neither on plain DOS nor
on Windows 98.  Perhaps `redir' picks up a different program: `test'
is not a good name for a program, as there are standard programs and
commands by that name (e.g., in Bash or in Sh-utils).  What happens if
you rename test.exe to some less-common name?

Also, what version of `redir' did you use?  Was it from DJGPP v2.03?

As for UltraEdit, I don't use it, so I cannot look into that.  But
since UltraEdit is a Windows program, and thus runs subsidiary DJGPP
programs in another VM, I'm not surprised: Windows does not deliver
timer interrupts to a DOS box that's in background, so perhaps when
the program runs under UltraEdit, it misses some of the timer ticks
when UltraEdit gets control?
