64-bit bug(s)

Hi Timothy, Hi All,

    I know some people have seen UI bugs with the 64-bit VM and image.
This is just to report that I see one very obvious bug.  In a recent
messages browser on 64-bits any attempt to select a method other than the
first in the list works, but immediately the selection reverts to the first
element in the list.  I suspect something in the event chain.  But it's
nice to have an obvious bug to chase instead of the much harder visual bugs
people have been reporting up until now. Hopefully the same root cause will
account for both bugs.  Fingers crossed.

Hi Eliot.

First thank you, thank you, thank you, for making my dream of developing on Squeak on a 64x64 bit system a reality.

The UI bug I had was from a custom-compiled VM. The cause was a rectangle such as 1@1 evaluating to random reals

1@1 inspect => 0.79@0.02
(exagerated for effect)

The effect was a "Modern Art" layout manager with no recognizable perspective and a refusal to abide by the norms of established practice. Picasso-ish.

When I upgraded to a pre-built VM from your site, the "fun rectangles" went away and where replaced with the "predictable rectangles" we programmer types like to depend on.
