Hey Georg.. I am a bit confused.. Why are you downloading the Shockwave player.. You only need the Shockwave Flash player..
Also.. I tried to open your url, it opened but it did not load, it just kept loading.. I can play swf from Safari from my sever but I haven't tried IE for a while since that seemed to cause other unrelated security issues.. We have changed to Firefox for Windows since that doesn't stuff up so often.. And, when we were on ebay, it was directed to some spam mob so the only option we had was to use Firefox..
I think there is a prob with your swf pano.. I do not get issues with others I have tried just using the swf.. The only time its not, is when using html5 since that has major coding in it for it to work..
if I go to adobe germany site... I only find Adobe Shockwave Player and its stated that the Flash Player is included. and after installation the flash test does succeeds. hmm..
I will try to uninstall IE10 Preview and try once again...
about Firefox. To be honest: personal I dont like it. to often I was persuaded to install plugins that later caused to many issues, slowing down the firefox by factor x even compared with IE or even caused crashes.
about chrome. Its GUI is so far away from common GUI feelings on Windows that I dont allways wanna switch... sorry not the youngest anymore... have to economize my time ;-))
... I was off IE until IE10, my first browser was lynx, my first browser with GUI was Mosaic and than ehthusiastic Netscape user... ;-) so lets see if its time again to switch ;-))
