DevalVR support

as a 3dstereo-specialist i must be interested in a perfectly working display also of 3dstereopanoramas .
i have mostly win2k-systems(several harddrives using independently(not at the same time) on the same pc. not only in win2k but also on my two winxp-systems i recognized severe Firefox-problems loading these two sites: i dont know yet other similar sites. dorin has two examples

multiple problems occured. they can be cured by deleting cache files.
could you pls add auto-deletion of cache-files in cross-eye-panoramas? normal users do not know what to do.
loading time of 60 secs is too long.
sometimes loading was speeding up when right-clicking. also images were shown.
on nl-site no loading-bar was shown-sometimes.
of course sometimes server and other problems could interfere.
i am looking forward to display my 3dstereopans with innovative devalvr-technology. for those not knowing yet. in contrary to qtvr, flashplayer(not every version) and java(used on my sites) devalvr-plugin-installation does not need administrators rigths/privileges.

after having strange anaglyph-like pattern i did a new winxp install.
site is now running properly with the only exception, like before:
in autorotation is a bit shaky. only deleting cache files helped. so the question remains. can autodeletion of cache files be programmed?
Problem in FF only. just rechecked. does anybody have no problem? i hav not the quickest internet.
thanks
