    Yes it is :)

    The glass thing you wrote about is slight scewwed, as glass will eventually fill a container it is stored in given time. Ever wonder why the window panes in very old houses rattle? It's because the glass has become thinner at the top as it has run.

    Nope, shrinkage is just caused by old age or cold weather :)

    If you actually measure the glass it is thinner at the top :)

    Conclusion
    There is no clear answer to the question "Is glass solid or liquid?". In terms of molecular dynamics and thermodynamics it is possible to justify various different views that it is a highly viscous liquid, an amorphous solid, or simply that glass is another state of matter which is neither liquid nor solid. The difference is semantic. In terms of its material properties we can do little better. There is no clear definition of the distinction between solids and highly viscous liquids. All such phases or states of matter are idealisations of real material properties. Nevertheless, from a more common sense point of view, glass should be considered a solid since it is rigid according to every day experience. The use of the term "supercooled liquid" to describe glass still persists, but is considered by many to be an unfortunate misnomer that should be avoided. In any case, claims that glass panes in old windows have deformed due to glass flow have never been substantiated. Examples of Roman glassware and calculations based on measurements of glass visco-properties indicate that these claims cannot be true. The observed features are more easily explained as a result of the imperfect methods used to make glass window panes before the float glass process was invented

    You seem to spend a lot of time crying Bruce :)

    Remember, real men don't cry, we don't eat quiche either. It's important :)
