Hello, wondering if anyone else has had this error.  I've searched online and cannot find any clues to a solution.

We have an invoice form.  It begins with a required form attachment, the invoice image.  The form is then routed to one of four next user tasks, depending on selections in the form.  The next user receives an email with the attachment image.  But when they open the form and click on the attachment, about 5-10% of the time the user gets this message: "Laserfiche Forms has encountered a problem. This account does not have sufficient rights to download form attachments." and when they submit that form, the completed task variable for the upload file field is blank and the attachment is missing from the form in the next task.  So the form drops the invoice image.

In this pic below you can see some steps from a process that dropped it. The image is in the original 'Form Submitted' step, but when I look at the 2nd completed step 'Invoice Approval Request', the field is blank.  The user could see the link in the second form, and it is a required field so the form also saw the variable to let the user submit it.

This form is large, has a lot of lookups, some CSS formatting and some java to update fields upon window load.  We also experience forms latency problems more pronounced at the start of the day. Could the lookups or scripts running be interfering with the attachment handler? 

I can't find any fault with the process diagram - it works most times but not others, no matter the file size, and no matter the user, no matter which task it is leaving and entering.  No errors that I can find in the server event viewer.

Any help would be greatly appreciated!
