problem with threads and toggle button

[Ionutz Borcoman <borco borco-ei eng hokudai ac jp>]

Hi,

My program have some toggle buttons that can set other buttons depending
on which button is toggled. Some of them can be also disabled. Checking
the run button, a thread is started and soem of the buttons are
disabled, including the run button. The pause button is enabled.

When I click the pause, I can suspend the thread. When the thread stops,
depending of several conditions, it can disable the pause.

Now the problem:

When the threaded function ends, I enter the main gtk loop to set some
of the buttons. i use:
  gdk_threads_enter();
  ....
  gdk_threads_leave();

This work almost always, unless I hapen to do this: keep mouse button
press down in the pause button when the threads ends and the thread
tries to disabled it. If I comment the line (from the threaded function)
that disables the button, then everything works fine, excepting I don't
get the effect I want. 

Any suggestions ? 

TIA,

Ionutz
