was using OSX 10.6 for years and when alert of impending event came up it gave a choice of interval before it repeated

Have upgraded to OSX 10.8.5 and the alert only gives the option of 'snooze' and decides on length of snooze itself

I relied so much on the 10.6.8 alerts I'd like to know any way of adjusting v6.0 to work as earlier versions

And, less important, to change hideous header colour with nat simulated torn page top
