Dang, thats a shame. From my website logs Opera seems to be almost as popular as firefox at the moment.
I have tried hard at solving the issue - but I have no idea why opera fails - can’t find any worthwhile logs either 
I’m guessing its their broken plugin interface.
I once had the same bugs in Opera that I had in firefox on linux . The problem was the case-sensitivity of the image names.
Works now after page reload to.
Forgot to mention: Using Safari for this.
Reload works, although I still get an exception in the logs when i click off the game.

No worries on that exception Endolf, just gonna have to live with that for a while.
I didn’t realise until now that applets that are reloaded can run in the same VM - interesting stuff.
Orangy’s messages about singletons and statics all come back with a sudden prominance! Lucky I listened the first time

Hmm, I upgraded to the latest Opera but still the same result it seems. Although I managed to find the java console (not sure if it’s a new addition or I just missed it before) it doesn’t have anything useful in it - in fact it doesn’t have anything in it!
Is it possibly worth pestering the Opera people to see if you could track down the root cause?
works fine for me on Opera (version 9, Linux), but gives me a grey screen for about 3mins before it starts after which it runs fine. so is a bit borked but at least it runs.
Same results as Kapta on Opera 9.02 on XP.
Kev
same opera issues here. though after 5mins of gray screen… it still doesnt start.
this is a definite Opera-specific problem. they shouldn’t wrap the Sun’s VM in their funky stuff just to avoid Sun’s UI and stuff
it’s bad enough they start their VM with , but what really stuck me as “tacky” is they also override the sun-specific tags!
anyway, opera needs to be contacted i think…
applet works fine here on XP, FF 1.5.8, java 6
I’ll try later on my macs

Strange, it pegs the CPU at 100% and I think the fps is ~0.5 or worse by the looks of the "swinging “click to start”. Clicking didn’t seem to start it. Testing webstarted works fine and runs very smooth. CPU load so bad that even mouse cursor freezes in-between.
IBM lap, WinXP SP2, Java 1.5, FF 2.0
Do you have a video card ?
His monitor would be blank if he had no graphics card

It’s an ATI mobility Radeon 9600. It could naturally be it choking on the semi transparent stuff in an applet… :-\ Might work if I just could get past the first screen… Bit strange that the game doesn’t register the mouse click at all :-[
Update: managed to get past first screen by clicking/holding in mouse button for ~1 min (not sure what did it). Game itself was just as unresponsive as menu, sorry. screen update every 4 - 40 sec or so.
Same issues reported on another ATI card.
Kev
Same problems here on an ATI X300 mobility.
Can’t really bring myself to believe it’s an ATI issue, but I suppose it could be.
Opera works repeatedly for me here now.
Kev
worked for me in firefox on win2k with a gf4mx.
Applet works fine for me:
Firefox 1.5, radeon 9800 pro - catalyst v6.7
So it isn’t a global ATi problem
