URGENT! - set_transient_for -

["Tom Knowles" <tom peters co uk>]

I am developing a touch screen app (no mouse or k/b) which makes the
following problem that much worse...
Initially, when displaying a dialog, touching any of the window behind
blotted out the dialog. This window had been made insensitive for aesthetic
purposes and thus stopped sensible use.
Havoc suggested set_transient_for.... great! that seemed to work.
However, when the dialog spawns another, not using set_transient revives the
original problem.
Using it causes strange positioning behaviour, ignoring any positioning I
try to apply!
Please, can anyone help me?
Thanks
Tom
