Dear Herbert:

Thanks for your willingness to take a look at this.

I agree.  I really like powerdot.  It's great.  I am using it all the time
for my new presentations.

It's just that I have 20 general chemistry lectures in seminar, and when the
semester comes, I just have enough time to update the lecture. It does take
some time to move over to powerdot.

> please provide a minimal example file.
Here it is.  Again, I really appreciate this.

Thank you again.

Warm regards,
