Phpstorm cursor jumping back constantly at long lines

Question

When I have a long line and want to type text at the end, the cursor constantly jumping back to the middle of the text, for example:
from here: to here: .
Is it a bug or a feature ? How can I turn it off ? My PHPstorm version is 4.0.2 (#PS-117.501)
