Mac automatically selects text after deletion

Question

Running OS X 10.9, although a problem arose in 10.8, and I noticed this in Xcode and Netbeans. When I select text and delete it, usually some variables or lines in some code, the selected area remains selected, basically choosing the next character set. So when I keep typing, I type this bit of the selected code.

For example, let's say I have the following bit of code selected between brackets: A fast [brown fox] jumps over a lazy dog.

Now, after deleting the text, the following text will be selected between the brackets: Fast [jumps against the lazy dog.

The expected result will be that the text will not be selected, and the cursor will simply be in the "J" field (or a space before) in the word "jumps".

I searched for this type of behavior in Netbeans and Xcode, but didn’t find anything, so I finish the behavior in OS X, but I did not find anyone else with this problem to fix it.

Thanks for any help.

This is an old problem, but it persists. This answer does not provide a solution, but the problem is recorded in the mail, which can help find the cause. First you see a successful mark and overwrite, and then an unsuccessful one. After that, I hit and repeat several times to show that the problem was recorded in the editing history.
