Not working in Opera

Hmmm, not working in Opera for me either. Damn Opera. IE6 should be fixed in 6.x-1.x-dev though.

This is the javascript error I am getting in Opera:

Event thread: readystatechange
Error:
name: ReferenceError
message: Statement on line 49: Undefined variable: SHARETHIS
Backtrace:

...
stacktrace: n/a; see 'opera:config#UserPrefs|Exceptions Have Stacktrace'

Could you try out 6.x-2.x-dev with Service Links 6.x-2.x-dev? There's a couple fixes in there that might help.

Anon is a hero. Please see #619964: Javascript errors on IE, FF, Safari as his fix was committed and update to ShareThis 6.x-1.7.
