Charan,
Most web developers don't seem to bother disabling general text
selection behavior in the browser, although admittedly it can appear
to be a nuisance at times.
GWT event handling (including previewing) isn't really designed for
unconstrained inclusion/exclusion use, as you are finding out.
Less elegant, but maybe you should concentrate on subclassing a subset
of the stuff on your page where you *don't* want to allow text
selection, handling those events in onBrowserEvent and avoiding using
the global previewer. Although this is more coding (and therefore
less elegant) I think it leaves you more in control. Once you get
event previewers fighting over correct behavior, I consider the design
to have failed.
