Patrick
thank you for your feedback
Are you talking about the "attach" button?
The feature you are describing works on intrapages.com so my guess is that you have something not working correctly in your envirinment, make sure you check the logview in the application and also the dominos view and tracelog.
Intrapages works locally as well, so try both using local and server to see if you get the same results.
Have you read the installation notes found in the start page when opening intrapages using a notes client?
My guess is that you are not allowing java operations
Yours truly
Thomas
