Sorry, my bad. I used the wrong terminology. When I said, "form", I wasn't
referring to a visual form (that you drop TLabels and TEdit's on), I was
referring to the white area named "components" that you have when you start
a new service application. I definately don't have any visual forms in my
service app.

As to using the timer. I have since figured out that I shouldn't be using
that, and converted my service app over to use it's own thread for the work
its doing, and removed the timer from the project and I'm now using Sleep.
It seems to be reacting a lot better now, however it is still using a lot of
CPU resources.
