well are you using the paypal generated code or are you using the BV pay pal buttons? that would be my first question. i use only the Pay pal generated code and copy and paste in a html box. examples of this are here:

these work great and you can look at the source code and compare it to the source code you are using.
the second thought i have is why don't you upload the newest version of bv. you state bv10 in your short novel. relax, just kidding
hope this helps,
