Making new cell default to 1 line in Mathematica 8

In Mathematica 8 when you open a开发者_如何学C new cell it gives that cell 2 lines by default. I find this terribly annoying and wish it would just opened 1 line. I've googled a bunch, checked out reference.wolfram.com, and looked through the Format>Option Inspector with no luck.

That is not usually true.

If you position your cursor to insert a Cell and start typing, no extra line is inserted.

Although (I must confess), I tend to start typing in a cell with an Enter :D
