tunnel vision there.. i would not want a new instance at all no, and you
have solved a number of other future issues there too, together with the
hide() advice earlier, the application is not enormous so it is probably
best to create all required windows at startup and show as required. the
shared data for widgets and work in the methods the window displays can
be supplied by the respective class functions as usual.. sorted! Just
for debug purposes, what happens if show() is called on a window that
is already showing? Shall i set flags to avoid this?
cheers.
Also i have an issue building version 1.3, seperate thread opened.
