I recently upgraded to Adobe Reader 7.0.7.  I can still read documents on 
the web and older .pdf files that I have saved.  However, there is one 
serious problem.  Many problems present a graphic image, or figure, with 
captions, and the captions no longer appear properly.  Instead of being able 
to read them, I see a series of extended European letters (the letters with 
the odd symbols running through them.)

For instance, in this document (Primer of Quantum Theory) there is a lot of 
gobbledygook above the graphs on page 5, yet I know that it is really 
SUPPOSED to say "combination of two sine waves"  But it doesn't show this. 
I get some unreadable extended character set.

Interestingly, when I copy this unreadable nonsense and paste it into this 
simple text window, the correct sentence appears!  So Adobe Reader 7.0.7 is 
*almost* correctly reading the document, but in some cases it can't figure 
out how to display the captions.

Any suggestions on how to fix this problem?  I really need this to work.

Thanks,

Robert
