RE: cygwin runtime woes

["Pierre Muller" <muller@ics.u-strasbg.fr>]

Tried it another way:

./gdb ./insight.exe

(gdb) run --nw ./gdb.exe

Insight starts but no source window with 'main' function code appears.

insight.log contains the folliwng:

$ cat insight.log

All seems to start with the failure to handle
iwidgets::scrolledtext command,
any ideas what this is all about?

 I tried reinstalling tcl/tk for cygiwn, no effect.
