Restore normal mouse pointer

Hi all! :)
In a frame I change the mouse pointer with an image, using the Cursor object. The problem is that I want, when the frame ends, the mouse pointer to become again normal. At the moment I'm doing like this:
End of Frame:
-Change cursor to standard arrow

But, after that, the mouse pointer is ALWAYS the standard arrow, even when it is over textboxes, when it should be I-beam cursor.
How can I restore the mouse pointer like if I've never used the Cursor object's actions?
Thank you in advanced! :)

PS: I've already tried not using the Cursor object, hiding the mouse pointer and using an active object always at XMouse,YMouse position, but active objects are always behind UI objects like buttons and textboxes.

I'm not sure that events work on frames that they weren't programed on. Try doing (start of frame): (Change cursor to standard arrow)on the frame you want it to be normal on. other than that I don't know.
If that doesn't work then use an active object with the mouse movement. it may be more difficult but you have more control over it.
