- /* Though the cursor is invisible until you move the mouse, extensibility pages get a mouseover event
-
- when they load. If your invisible cursor is over a focusable item, this mouseover event can cause the
-
- focus to land on the wrong item when the page loads. The bFirstMouseover variable (originally set in the
-
- MoveFocus.js file) is used to identify that initial mouseover event and nullify it.
-
- The first mouseover event fires when the page loads. Then there is a statement in the
-
- StartFocus function, in the MoveFocus.JS file, which uses the setTimeout method to wait until
-
- after that first mouseover event fires and then resets bFirstMouseover to false, so the subsequent
-
- mouseovers will be handled normally */
