Good evening,<br><br>OK, I'm just going to bite the bullet and ask here since I got nowhere with Google for this problem. I'm hoping someone can help me figure out what I'm doing wrong with Beamer. Probably very simple and obvious, but when you can't get something working right, it just gets more and more frustrating. I'm using MacTeX with TeXShop on OS 
10.4.10 on both a PowerPC and an Intel laptop. I have no trouble compiling other documents, but I can't get anything using Beamer to work on either machine.<br><br>I followed the Beamer installation instructions included with the package, and I have recent versions of pgf and xcolor as the package requires. If I try the minimal example given in the Beamer installation instructions (copied below), I get a very long list of things in the console, ending with an undefined control sequence (the whole console message is posted below also). This is the same result I get if I try any Beamer document, and I don't know enough about the inner workings of LaTeX to figure out what I'm doing wrong.
<br><br>Any guidance much appreciated.<br><br>Thank you,<br>Linda Lanz<br><br>%%%%%%%%%%%%%%%%%%%%%%%%<br>%!TEX TS-program = pdflatex<br><br>\documentclass{beamer}<br>\usepackage{beamerthemesplit}<br><br>\title{Example Presentation Created with the Beamer Package}
