Adobe mysteries

[Stacy Pober]

I am just starting to use Acrobat files and I have two questions: 

1) Why do files created in Acrobat 4 and 5 look so crummy in the 
Acrobat v.3 reader?  Is there any way to 'fix' this?  (I can't 
control the version someone is using on their home computer, and 
there are a lot of people who haven't upgraded from v.3).

2) When you choose "Export" and then request that the program delete
the pages, does it really save it in some history list?  I ask 
because we had a weird experience today.  We decided to split a
pdf file into two sections because of file size concerns. Went 
into Acrobat, exported (and chose 'delete' in the Export menu).
Saved the original file. Saved the Exported file.  The original 
file, when viewed in Acrobat, looked fine and had the right
number of pages - but the file size had not changed at all. 

When we went in and instead chose to export the full document to
a new file, the file size was correct.  My best guess was that 
Acrobat saved the deleted pages in a section of the file that 
contains revision history so you can 'undelete' it.  But I have 
no evidence of that.  It's just a wild guess.

Anyone know what caused that?
