Re: gtk 1.2.4 breaks my applications :(

[Mikael Hermansson <mikeh bahnhof se>]

There are also two other redraw problems with gtk+-1.2.4

Menus

* Sometimes when I am open a menu the menu items will not show up.
  It only shows a blank box without the menu text. This happens on all
  gtk and gnome applications.

Widget Resize: 

* Some of the gnome panel applications will not resize. and leaves only
  a 1x1 pixels window. (For example the modemlight applet)
