A while ago, I updated from 10.2.3 to 10.2.6, but because I was having modem problems straight after the update I replaced my 10.2.6 internalmodemsupport.kex extension with the 10.2.3 version.
Things started clearing up and the modem worked. Moved the 10.2.6 modem extension back, but upon restarting my Powerbook keeps asking whether I want to 'fix and use' the extension.
How do I fix it so that it's fixed once and for all, because whatever I choose it keeps asking after a restart?
