Windows XP SP1, OEM install at present, I did a bit to my taskbar. Now, it is too broad; that is, it is two times as broad / wide. Generally, it uses one row. But at present it use 2 rows. If I try to decrease the size, my only selection is "0", [no] thickness. I want to make use of the "quick launch tool bar". I have that enabled. To the right of the quick launch [QL] icons are 2 columns of dotted lines. To the right of the 2 columns of dots, there is empty space until one reaches the system tray. Below the QL icons is one more set of dotted lines in 2 columns? Every column has 4 or 5 dots. I'm not at the PC, at present. This 2nd row emerge when I open a window [IE, OE, "my computers", etc]. The task bar is not locked. Auto hide is disabled. "Leave on top" is enabled. Groups are not chosen.
I can't make use of system restore because I installed a few programs after this trouble occurred. The language toolbar is too enabled. If I uncheck it [right click on the task bar, left click toolbars, left click language bar, the language bar returns after I reboot.
