GTK+ and the NVIDIA 337.25 Driver.
 

I was reading the "Release highlights" for the NVIDIA 337.25 driver and came across this,

Does this apply only their GUI settings utility?

Thanks.

That's the way I read that statement.

Mmm-hmm. But the current version of gtk+2 is 2.24. 2.4 was last updated in 2004, and 2.2 is 'known unto God' (as the WW1 headstones tactfully put it) ... so whatever Mr. or Ms. Nvidia is actually trying to communicate, it would seem that they aren't successfully communicating it.
