{{blk2blue.jpg|blk2blue.jpg}}

The **PrimaryBufferRestoreRequired **method returns TRUE (1) if the buffer pointer of the Window Component has been changed. This allows synchronization of the saved buffer with other Window Manager threads.

**Implementation:**

The **PrimaryBufferRestoreRequired** method calls the SELF.Primary.Me.RestoreBuffer method to restore the primary buffer in the WindowManager's ResetBuffers method.
