I want to modify pointer

Hi,
I was having trouble with selecting


in above case, if faces are zoomed that close I can choose it without problem, but if I zoom out, the pointer’s three arrows block the view of faces, and I can’t choose faces close to pointer arrows.

how can I adjust the three arrows of pointer, or the size of pointer, or choose next faces easily?

Thx ahead.

Turn off the widget with Ctrl+Spacebar or icon on 3d view header

File / User Preferences / Interface, change the size of the Manipulator

Thank you~
