My computer has been killed. I suspect a virus. Whatever the truth, one minute it was chugging along fine, the next minute it wouldn't let me work any of the programs or sign off. So posting for the foreseeable future will be desultory.
I went out and bought McAfee brand Norton Antivirus, but since (I remembered too late) my CD drive has been broken for months, it didn't help much. Although I can hardly afford it, I may need to get a new computer. Some classes at State School require Internet participation.
