       Status:  new     |   Component:  pidgin (gtk)
      Version:  2.5.4   |    Keywords:

 The Problem: [[BR]]

 When i start Pidgin and open a menu and then click on a submenu before it
 automatically opens the submenu wouldnt open at all.
 I had this problem on vista 64bit and openSuse 11 32bit.
 [[BR]]
 The following submenus have this issue:[[BR]]
 - Plugin menus under the Tools menu[[BR]]
 - 'Activate Account' under the Account menu[[BR]]
 - all account submenus under the Account menu[[BR]]
 - all Plugin menus on the tray menu[[BR]]

 What i did about it:[[BR]]

 When a menu or a submenu gets created
 {{{
 gtk_widget_show(menuitem);
 }}}
 is called on it. That was the Problem.
 When i removed all this calls and placed a
 {{{
 gtk_widget_show_all(parentmenu);
 }}}
 later when all menu creation was done the clicking problem disappeared.
 For the tray menu a
 {{{
 gtk_widget_show_all(parentmenu);
 }}}
 was not necessary because it is already in the code.

 ----

 In the attached patch i also 'fixed' a windows issue where the tray menu
 wouldnt disappear: When you leave the tray menu fast with the mouse
 {{{
 docklet_menu_leave_enter
 }}}
 does not get a
 {{{
 event->type == GDK_LEAVE_NOTIFY && event->detail == GDK_NOTIFY_ANCESTOR
 }}}
  message. Instead it gets a
 {{{
 event->type == GDK_LEAVE_NOTIFY && event->detail == GDK_NOTIFY_UNKNOWN
 }}}
 message. So i added it. It works for me, but i dont know if it is a good
 idea to add it.
