Hello, I've been experiencing a problem with various programs for some time. These programs use the GTK+ toolkit and when a particular menu is selected from the main menu bar at the top a sub-menu of either very small height or of no height (i.e. a thin line) will appear. Needless to say, the program cannot be operated with such menus.
Usually, a program restart will fix the issue and restore normal menus but sometimes several restarts are necessary. The error message that is associated with these botched sub-menus is the following: Gtk-WARNING **: gtk_widget_size_allocate(): attempt to allocate widget with width 226 and height -118. Somehow, the menu is being invoked with a _negative_ value for height, which of course makes no sense. The resulting menu widget appears as a thin (one pixel) horizontal line. Through searches I've found nothing similar reported Because this can happen with more than one program, I doubt if it is the fault with any single package. GTK+ must be causing this. Has anyone experienced similar behavior? As I mentioned, a program restart usually fixes the problem. However, when and if this problem will occur is not predictable. It happens only occasionally and never consistently. Frank Peters
