I guess you couldn't be more specific about what 'Most everything' means?

When I tag an Email it tales 30 seconds before the tag appears. If I open a down loaded Email it takes 30 seconds or more before it can be read. During the wait the screen will not scroll.

Is it possible you're running out of memory?

How do I check memory? Why yesterday did it work well, the first time in a month, and today back to the same old problem. S C O T T
