Error on gdk_gc_predraw with devc++

["www.hiebun.com" <bkna besta cc>]

Hi all,
my application with Gtk+ on linux runs without any bugs.
I ported it on MS WinXP by DevC++.
Everything works well except mouse related ones.
Usually, I have the same error message,
"Gdk-ERROR **: file gdkgc-win32.c: line 1340 (gdk_gc_predraw): assertion failed: (data->xgc == NULL) aborting..."

Is that mean Gtk+ on windows not yet on this function?
If not, how can I solve it?

In my program, there are several video displaying windows and buttons.
I click mouse buttons to change the size of displaying widow size and the status of toggle buttons.

I am a newbie on MS Win32 environments.

Please help,
Regards,
bkna.
