Subject: Does Insight Actually work or is it just an alpha or pre-alpha?

has anyone actually been able to use Insight to do debugging?

I have downloaded the latest and greatest pre-built version for windows95
and haven't been able to use it at all.  Nice GUI but useless because

1. Breakpoints don't work
2. Can't load .exe's for debugging
3. Show's all source in Assembly.
4. Execution stops with error 193:
5. Single stepping doesn't work

Let me elaborate:

1. Breakpoints don't work:

run gdb from a bash prompt with executable name as argument: BASH.EXE-2.04$
gdb foo
...Insight gui pops up showing source code foo.c  ... set a break point in
main at the first
instruction,...click run, then nothing happens, execution doesn't stop at
the breakpoint,
focus moves to last line of main() being highlighted and the red breakpoint
marker there being
on.

2. Can't load .exe's for debugging:
...run gdb like so: BASH.EXE-2.04$ gdb
...gui pops up...from file menu choose Open...browse to and choose an
executable to debug...
source is all displayed in assembly, cannot switch view to 'source' the file
list at bottom
of the window has bunch of files not associated with your program
like...libccrt0.cc, mount.h, _ansi.h...
and so on.  Execution will stop at a breakpoint, but when trying to single
step, program seems to
run to completion and doesn't stop at the next instruction.

3. Source code in Assembly:
...when loading .exe's from commandline like so: gdb foo  source code is
shown C but when loading
from file->open menu only viewable in assembly.

4. Execution stops with error 193:
load an executable into gdb for debugging,
open the console view
(gdb) file foo
(gdb) break main
Breakpoint 3 at 0x2704: file foo.c, line 50.
(gdb) r
Starting program: /lab5/foo model1
Error: Error creating process /lab5/foo , (error 193)


5. Single stepping doesn't work:

...Same as above, can't step into a program. Have to set a breakpoint first
I assume and then
run...but I think this is just the way gdb works right? In order to step you
have to first 'run' the program.
but would be nice if you could step into a program without having to set any
breakpoints.
Sometimes what happens is the execution breaks in one of the cygwin files
and Insight window is
showing source like this:

- 0x40374f <cygwin_crt0_common(int (*)(int, char **, char **))+47>:
- 0x403754 <cygwin_crt0_common(int (*)(int, char **, char **))+52>:


I would really like to use Insight to do debugging but so far it's useless
to me besides having a nice
GUI.  Can anyone give me any suggestions to resolve these issues?  Initially
I was very excited to see
such a great looking front end but that is starting to fade unless I figure
out how to make this thing work.
The online help is so minimal, doesn't help much.
