PowerPointin tekemät html-versiot toiminevat hyvin ainakin v. 4.0 tai
sitä tuoreemmissa IE-selaimissa. Muiden selainten kanssa on hieman
ongelmia. Sorry. 

The html-versions made by PowerPoint should work well with version
4.0 or later IE browsers. Other browsers may have problems with them.
Sorry.
