Reader 8.0 and LiveCycle 8.0

[#1]

I have created a fillable form with Livecycle 8.0.

When I have published it it seems to work fine in reader 7.0 and everyone can send it back to me using the submit button.

I have found that in reader 8 its `hit and miss` whether you can send it back it seems to just sit there and do nothing.

Please help !!!!!!!!!!!!!
