Since a DSL tech shared my laptop a couple of weeks ago to resolve a problem, I can't copy any text from any website to paste elsewhere. Instead, I get a plus symbol and then have to "clip" the highlighted area. I don't want to clip - I need to copy and paste. Can someone help me please? I have Windows XP. I'm sure it's just a matter of changing some setting, but I have no clue which setting it would be.
