With Babylon theme Tech's stars become red X for me but the forum does look crisper.
Yep, that's IE8 for you 
You can see the asterisks still though...
Its not IE8 
Each theme has its own image folder.
Inside that folder are the images for that theme.
The starfile images (rank images) for Techs stars are not in the folder for the Babylon Theme so they are showing up as red x's - Im sure if Tech asked them they would copy them over to that folder too.
The online/offline images are totally separate and exist in all of the themes folders so you are having no problem seeing those.
(I run a simplemachines forum so I know the paths/folders - thought I'ld clear that up for ya)

Fair enough, I don't run any forum, so have no idea, thanks for the correction

I suppose I should have said it like this then:
Yep, if you use IE8, because it cannot handle the missing image - firefox just deals with it...Yes!! Firefox wins

Man... should I complain about my stars or this is too much useless self-worring...
Yes, and the colour of your name - You've got to stand out
