Yesterday, Saturday, I downloaded a spell-check program suggested by Chris_.
It however never seemed to "take," and the computer started acting jerky at times, and so I "uninstalled it," following the directions for such a procedure.
However, when it was uninstalled, the tool-bar still stuck around at the top; I couldn't get rid of it excepting on a page-by-page basis (i.e., whenever opening a new Window).
The program's not there any more, but its tool-bar stubbornly remains.
How do I get rid of the damned thing? I'm sure it's creating all sorts of issues with this computer, issues this computer didn't have until I installed the program and then uninstalled it.
