Hello Angela,
"Slow" is a relative term.
Compared to the performance you had yesterday? Compared to ACCPAC Plus? Compared to your expectations?

If the "slowness" is new, then what has changed? Specifically, check the settings of your virus scanner, and make sure it is not checking your Adagio data files.
Is there a particular function you find is slow? If so, what is it?
What hardware are you running Adagio on? How much memory (RAM) is in your machine? What is the speed of your network connection? What operating system are you running? What else is your machine doing (besides Adagio)?
Sometimes there are some quite simple steps you can take to improve the overall performance.
