Hi, 

I found out that this one runs well on acrobat 4 (exchange), works but with
messages on acrobat reader 4 CE, and works ok on acrobat reader 5 [i have
no acrobat exchange 5 here]. I wonder if this file works ok on acrobat 4
for linux. Since max os x has a pdf screen driver, it should be possible to
write gadgets like this as os extensions.
