[Pro] Strange problem with taskbar.

[btcomm]

I searched for this, but I'm not sure what I should have searched for and maybe someone has a quick answer. I raise my taskbar so that it's 4 lines instead of 1 and then I lock it. I reboot and it will go down by 1 line. Reboot again it will go down by 1 line again. Next reboot same thing until it's only 1 line again and it stays at one line. I thought I remember someone having this problem before. Does anyone know what causes this? I have windows xp pro.

If anyone isn't sure what I'm talking about let me know I'll try to explain it better. I guess I could post screen shots.

Taskbar1 is when I change it to 4 lines.

Taskbar2 is what it looks like after 3 reboots.
