Time in Service

[Microsoft]

I'm creating a service and am using a timer in it. When the service starts
I enable the timer, and then in the timer elasped event, I'm disabling it
(this.srvcTimer .Enabled = false) so the timer event doesn't fire while I'm
already in it. At the end of the timer elapsed event I re-enable it.
However, while running in the debugger, the event never fires. If I comment
out the line disabling the timer in the elapsed event, the event fires. I'm
not quite sure what I'm doing wrong if anything.

Here's the code in question, and the appropriate lines in the elapsed event
are commented... the event in the last bit of code at the bottom...
