Sub-windows on top

[Nicolas SABOURET]

Hi !

In lyx 1.1.6, all sub-windows (e.g., latex-preamble, math-panel,
characters-layout ...) are on top of the main LyX window. However, this
was not the case in previous version and I prefered it before.

Is it possible to go back to the previous version (secondary windows NOT
on top of the main one) ?

Thanks,
        Nicolas Sabouret

(PS: I read about this in lyx-user, but I couldn't find any "we're
working on it" answer. Therefor, I report this as a bug ...)
