    The problem seems to be that under some installations of win95, MS-DOS
    programs do not close the MS-DOS window by default when an application is
    finished running. The Triangle mesher is an MS-DOS executable that femme
    calls to make the finite element mesh. On win95 systems that are configured
    this way, femme hangs when you mesh or try to evaluate a problem, because the
    program spawns triangle and sits around waiting for it to finish, which it
    never does because the MS-DOS window that it is running in never closes.

    Although a couple of people have reported this happening, I've never been
    able to reproduce it on any of the machines to which I have access. I've
    recently discovered a different way of calling Triangle that forces the
    MS-DOS window to close when the mesher is finished running, and it reportedly
    fixes the problem.

    I will include this fix in the next release of femm. In the mean time, if
    anyone out there is having this problem, email me at dcm3c@aol.com, and I
    will send you a version of femme that is patched for this bug. Many thanks to
    gascon@cnrs-orleans.fr and pekr@magneton.cz for helping me root this one out.

    Dave.
