Cannot see the Cursor when posting.

Is it the same with everybody else ? When i post and first press for example quote-function and want to go back with the mouse-pointer to the grey window to continue posting, i cannot see the cursor. it is nearly the same grey color like the window where you type the text. Only when you put the cursor over already written text, it becomes bright white.
Can the color be changed to something else then grey ? Sometimes it is like a hide and seek game.
