Long time no see.........
From reading the "tips" on the puzzle site I suspect you would be better off trying to stick with IE. Not Mozilla friendly (Netscape).
I think I read you have the latest Shockwave & FlashPlayer plug-ins right for your OS?
NP-PPC-dir-shockwave
ShockwavePlugin.class
Shockwave flash NP-PPC
When I had OS 9.1, I played my "java & Shockwave/Flash" games using IE & iCab. For some reason Netscape & Mozilla were a little flaky when it came to playing those type of games.
Try the following with IE (you may have already done some of the things listed):
Once a week in IE Edit>Preferences, delet History, Empty Cache (if you have cable set Cache to 0).
Once a week Go into the system folder>preferences folder & trash the following preferences:
finder
ASLM
PPC Registration Database
Cache.waf-found inside the MS Internet Cache folder
MRJ Cache folder-a new one will be recreated.(If not found go to System folder>Application Support>MRJ Cache folder-trash all you find inside-(
DO NOT TRASH THIS FOLDER)
Download Cache-found inside Explorer Folder
Downloads.html-found inside Explorer Folder
History.html-found inside Explorer Folder
Rebuild your desktop w/extensions off. Use
Techtool Lite or
Trash*Desktop - may delete Finder comments to rebuild your desktop w/extensions off. Does a better job than manually & you avoid all the finger gymnatics. You just have to hold down the shift key to shut off extensions.
Restart to turn the extensions back on again & empty the trash.
If you want to rebuild manually, see KB article

Good luck!
