When encrypting a PDF document with a user password and the option to prevent text from being copied, the Adobe Acrobat Reader version 7.0.8 reports an error (but continues to run). The error is:
Could not find the XObject name "WPToolsJIF_1".
Note, the _1 varies, for example, it came up as "WPToolsJIF_73" once.
If I allow text to be copied from the PDF, I don't get this error.
