A new source distribution is now in place at http://home.earthlink.net/~jrcarter010/mindet.html (or through the link at www.adapower.com) that should correct this. Were you able to run the Linux executable release? Some users running the Win32 executable report the window disappearing as soon as it occurs. One possible reason for this is that the executable was built using GtkAda 1.3.10, and the users have GtkAda 1.3.12 installed on their systems. This can be alleviated by insuring that the executable loads the DLLs that come with the executable, or by building from source. -- Jeff Carter "My brain hurts!" Monty Python's Flying Circus
