I cannot reproduce that part. from oxygen-demo5 (that you can get by manually compiling oxygen code, or possibly there is even a package for it somewhere), I am unable to make the mdi freeze. Also not that in Qt Designer, the main view (in which newly created widgets/window forms appear), is a QMDI (and mdi subwindows). As far as I know, these do not freeze (unless you start adding mdi in the inside subwindows). Or do I miss something ? Reason why the full window (and newly created forms) freeze after the first mdi freezes, it is a consequence from the fact that the main view is also mdi. It gets screwed at the same time the inner mdi is. ... still investigated. But if you could have either code snipset/example application/ui file that demonstrate that MDI freezes without stylesheet, that would also help.
