How do I stop iCal from automatically converting manually entered times into entries on my hourly calendar?

I use the monthly calendar view in iCal.

I enter an event as such: "lunch with mom @ 3" so I can just look at my monthly calendar at a glance and see what time things are.

In the latest update, it now automatically strips that entry of "@ 3" and converts it to the hourly calendar, which I never use or want to look at, adding a layer of clicking between me and the info I need.

Is there a way to turn that off? Or do I just need to find a new calendar app to use and/or never update any Apple software again for fear of them changing the features I use?
