The mouse on my computer seems to have a cold and I am having great difficulty navigating with it. The extrenal mouse I purchased yesterday seems to make the situation worse. Being a computer Luddite, I am clueless as to how to fix the problem. Additionally, I am on vacation and do not have my usual, reliable computer doctor nearby so I will be searching for a new computer doctor who might be able to fix it. Hopefully, all will be well soon.
