For Question 1, to view the slide show on current slide, click on the Slide
Show icon at the bottom left hand corner of PowerPoint. If you click Slide
Show > View Show, it will start from the 1st slide instead.
For Question 2, this can be easily done using PowerPoint 2002/XP and above,
where you can add entrance and exit effects. For PowerPoint 2000, you
probably need to add one item on each slide, then add appear/dissolve effect
to every item. Then, click Slide Show > Slide Transition. Have the slide
advance automatically after X seconds. (where X is the set time)
For Question 3, you can work on PowerPoint 2000 presentation in 2003. But
PowerPoint 2003 contains new animation effects that 2000 does not support. To
ensure that your presentation will work between 2000 and 2003, disable the
new features in 2003. To do so, open PowerPoint 2003, click Tools > Options.
Select the Edit Tab. Under Disable new features, check all the options.
