Starting a sketch

Hi,

In SW2008, for some reason my system automatically selected the front plane when I clicked on a sketch tool - I liked this a lot, as my parts do not require multiple user interfaces and plane recognition

In SW2012, the sketch plane always appears as an isometric propagation, and I have to select the desired one - how do I prevent this and tell the program to present the front plane parallel to the screen as a default setting?

It's a small thing, but a big irritation when making many sketches every day.

Thanks
