I've noticed that if I leave a document open for a couple days (i.e., in word or excel) when I log into my computer, it is running very slow. It has happened on the past couple computers I have worked on, but couldn't really pinpoint the problem.
At the end of the day, instead of saving everything closing out and logging off... I just save my document and lock the computer with ctrl+alt+del. The next day I come in, everything seems to be working as it should. Then usually on day 3 of the document being open, I notice my computer is very laggy until I close out of my document.
What in the world would be causing that?
