To add to David's comment...

When the timer() method fires, you should disable the timer before you run your process. This prevents potential problems of the timer firing again while the process is running:

*timer() method
local lnInterval

lnInterval = this.interval
this.interval = 0            && or you could: this.enabled = .f.

* call your process here

this.interval = lnInterval   && or you could: this.enabled = .t.
endproc
