<p>PROBLEM TO BE SOLVED: To improve the operability by erasing the window, which is opened in response to the window open request, at the time of moving a cursor to a position which is a prescribed distance or longer away from the position where the cursor existed at the time of issue of the window open request. SOLUTION: When the window open request is issued a detection means 15 reads the cursor position detected by a cursor position detection means 13 to detect the cursor position for issue of the window open request. After this detection processing, a discrimination means 16 reads the cursor position detected by the cursor position detection means 13 to judged whether the present cursor position is the prescribed distance or longer away from the cursor position detected by the detection means 15 or not. If the discrimination means 16 discriminates that the cursor is moved for the prescribed distance or longer, an erasing means 17 issues an instruction, which erases the window opened in response to the window open request, to a data processing means 10 to erase the window.</p> |
