SlideShow: how do I use a Timer?

I tried to use a Timer in a SlideShow Desktop application, but I failed miserably.

The only example with Timer is related to Thread…

In http://documentation.xojo.com/ I typed Timer and get just that: the Timer page. Do not look at the example there…

Help ! (or Hilfe, Aiuto, à l’aide, etc.

I changed my loop indice kind (from Dim to Static) and wait a bit: the Timer works fine.
