Abstract

A method, system, and memory for reshaping a window using a drop-down scroll bar are provided. The method includes the step of dynamically reshaping the frame of a window around information within the window in accordance with a preference setting and in response to scrolling the information using a drop-down scroll bar. The system includes a display for displaying the window, a processor, and, in response to a command from user controls means for controlling the processor to reshape the frame of the window around information within the window as the information is being scrolled. The memory includes computer readable program code that is stored in the memory. The computer readable program code provides instructions for reshaping the frame of a window around information that is being scrolled in that window.
