PPT with animation requires two space presses to advance

[r042wal]

I am trying to find out what I am doing wrong with my Powerpoint presentation. I have an text box object that I selected and animated with the 'float in' effect. When I run my presentation, I have to press the space bar twice to advance to the next slide with the animation. Otherwise, everything works fine. What am I doing wrong that I cannot advance to the next slide with just one spacebar? If my slide does not have an animation it advances with just one press of the spacebar.



Thanks in advance.
