how to disable dim changes

Hi,
there are many times that i want to change something on a dim in mymodel, for example, decimal places, add dual dim, add brackets,link values, etc. in 2008, i keep getting frustrated cause when iclick on the dim it goes into editing mode, i.e. change value. (seethe attached jpeg). when i click on the dim once, i don't get tjhechange to change the things i mentioned above. is there any way toset this so it lik e2007 and before, i.e. click twice to change thevalue, not once?

thanksSolidworksGeneral
