Summary: tk_getSaveFile run with fileevent through a process hangs wi

Initial Comment:
not registered... be...@wa...

From Comp.lang.tcl:

OK,  I am running ActiveTCL 8.4.4.0 on Windows XP 
Professional.  The
following two scripts recreate the problem on my 
machine.

runme.tcl:

    set r [open "|wish ui.tcl" r+]

    after 500

    puts $r "save"
    flush $r

ui.tcl:

    proc msg {} {
     gets stdin r
     if {[eof stdin]} {exit}
     eval $r
    }


    proc save {} {
     tk_getSaveFile
     update
    }

    fileevent stdin readable msg

I have attached them as well.

This looks like an issue with
Tk, not Tcl.  Please file the
report with the tktoolkit project's
tracker.

FYI - this also hangs the second GUI on Win2K, but in this case
it hangs before even displaying the save  dialog. Also - I added
some color changes to each section to see whare the hang was
occurring & if I added calls to update in the msg proc it
actuallly
crashed the executable. without the updates, the last color
diplayed was the one set immediately before the tk_getSaveFile.
