Depends what you're doing, but to prevent that, you can use a form or combo class property, say, Listval.

In Init: this.Listval = this.list(1)

in Click:

if this.value != this.Listval
  this.lostfocus
endif

In Lostfocus:

this.Listval = this.value
...other code

As I say, I'm not sure the exact circumstances, but that's one other step, maybe...
