Strange... Have you done a clean checkout and a clean bootstrap?

For me it happens also with rev.100787 on

Now, to open an item (File, Edit, Options etc.) on menu bar, one MUST 
click on it (with mouse-1) and HOLD mouse-1 pressed, otherwise the menu 
does not remains opened, but it is closed in a fraction of a second.

Perhaps, one of these changes is the cause:

----------------------------
2010-07-09  Jan Djärv  <jan.h.d@swipnet.se>

	* xmenu.c (set_frame_menubar): Must realize menubar_widget to get the
	correct size for Motif.
	(free_frame_menubar): Call x_set_window_size to update frame size.

	* xfns.c (x_window): Set borderWidth to 0 for pane and
	EmacsFrame.  Frame size calculation is wrong otherwise.
----------------------------
2010-07-08  Jan Djärv  <jan.h.d@swipnet.se>

	* xmenu.c (set_frame_menubar, create_and_show_popup_menu)
	(create_and_show_dialog): Don't call apply_systemfont_to_(menu|dialog)
	unless USE_LUCID.
