Re: Performance issue with new gtk 2.0 for win32

 Tor,

 Thanks for the reply.

 I actually trust people's code more than my own :(. So I guess I will have to
go to my app and track malloc, g_strdup,  and the like and do what you are
proposing, i.e. match with a g_free.

  What I see in my app running on Windows is that the memory just keeps growing
 and growing and growing.

  I did notice something REALLY interesting today. The memory was up to 87MB
and when I "stopped" (i.e. I have a timeout_func that I can start and stop with
a button press) my application, it went back to 3MB.

  This leads me to think that :
  1) Win NT Task MAnager is bogus (more likely)
  2) Gtk/GDK/GLIB libs free up memory chunks when they age ???? (Unlikely huh?)

  This is driving me nuts..  Any sugestion as what it might be happening ?

 Thanks for the help.

  Harring.
