I don't think we can in this case. We need to force the console window that the command shell inherits to be hidden to avoid clutter on the screen. It appears that this has the side effect of hiding GUI apps that are run directly from the shell, unless the user remembers to type "start freecell" instead of just "freecell" to run the GUI program asynchronously. Since subprocess support is intended primarily for command-line programs, hopefully this isn't a major problem although it is certainly unfortunate. It doesn't happen on Windows 95 though. Doing a little more experimentation, it appears to be specific to the standard NT command shell as well. If I use a cut-down shell program I wrote for testing, the problem doesn't happen. ---- This is probably a good time to mention that I am intending to submit a change (hopefully for the next release, if it's not too soon) to the subprocess support code that will allow Emacs to run multiple DOS programs on Windows and to interrupt them - the inability to do these two things is a major limitation of Emacs subprocesses on Windows 95 right now. BTW, is there a way I can update my 19.34 source tree to match the FSF source? I'm thinking of when Geoff submits patches to change "win32" prefixes to "w32", which will probably be before I submit my changes - it would mean my patches could be applied directly.
