yup must be flash-prob...
i installed complete new system 2 weeks ago, but with same software like on old system... even used the same installers.
i just went to office to test with a dell-laptop .. same problem too, resolume crashes at once while dragging *.swf files to a deck.
just one was playing out of the flash folder inside resolume... all the others from same folder crashed, too
was is odd to me, too: if i doubleclick a normal flash-file media-player-classic tries to open it and does nothing else than saying buffering 0% . if i open it with mozilla, it playes without problems...
is there maybe another flashplayer to use?
