What should I do if the xp taskbar becomes a double layer?

Yesterday, a user who used XP system reported to Xiaobian that his computer screen display taskbar is double-layered. I don't know if it was caused by clicking on that place. It looks very uncomfortable. How can I recover it? Down, Xiaobian and everyone will introduce the solution in detail.
Analysis of the reason why the taskbar becomes double-layered: In fact, when everyone uses the taskbar to cancel the lock, then dragging the taskbar and then quickly launching and the language bar position results in a double-layer display.
1, the first thing you need to do is to right click the mouse on the taskbar, click on it to see the "Language Bar" and "Quick Start" in the toolbar. Cancel the selection. After clicking Cancel, you can drag directly. Move the taskbar.
2, after dragging with the mouse, do not let go, drag to the appropriate position, then let go of the mouse, after reaching the appropriate position, we can select the "language bar" and "quick start" in the toolbar again and then proceed The addition is complete.
3, if you feel that the position is still wrong after setting, you can use the same method to adjust.
