I tested Qt 4.3.2 which was released a few days ago… basically everything works fine, but somehow the ROM state filter is extremely slow when Qt 4.3.2 is used!? I have no clue yet what could be causing this, but obviously something relevant has changed between Qt 4.3.1 and 4.3.2…

Anyway, all I want to say is keep away from Qt 4.3.2 for now – at least for QMC2 and until I’ve found the reason, a workaround or fix !
