The OSX 10.3 desktop icons acquire a square halo when highlighted. I feel like it distracts from the elegant appearance of OSX. Is there anyway to turn off these unsightly halos, or is this a permanent change, does anyone know? OSX 10.2 did not do this. For Titanium PBs, does OSX 10.3 affect the fan usage. I am currently using 10.2.8 and the fan on my 15" PB runs constantly, even just while reading emails offline or doing simple word processing.
