You told me (and confirmed) the problem was introduced in version #244, while it was actually introduced in #263.
This misled me for long.
Now I finally fixed the problem, and you will see it in next release (267).
It was not related to the 64bit thing.
As a general tip: when you click on the tray area and the extra icons are displayed in the little box, you can drag&drop these extra icons to the bar below. This is much faster than opening the dialog as you are doing.
