- Well, I just confirmed it: 4dos 4.0X crashes the session when called
- after OS2Speed is loaded. So with 4dos as my primary dos shell loading
- OS2Speed, things work fine, but as soon as some program tries to
- shell out (with 4dos as the SECONDARY shell) I get a crash. I don't
- get the problem with command.com (though I do if I load OS2Speed from
- a command.com shell and THEN run 4dos).
-
- One option that I've checked (with a good result) is to set
- COMSPEC to command.com so that secondary shells are not 4dos. I'd
- certainly prefer to have 4dos as the secondary shell too, but I'll live
- with this... Still, if any of you can think of a better solution, let
- me know.
-
- Hmm...now which author do I complain to?
