Updates to Attachment doesn't trigger After Update macro

[emmafa]

Hi
I want to save all information from a table row into a historyTable when an update is made to it (to be able to view the history of the table).
However the table contain one field of data type Attachment and changes to this field doesn't seen to trigger the After Update macro.

How do I save changes to an Attachment data type?
I want to use a macro directly from the table rather than using code triggered by the update form since I don't want the history saving to be bypassed by people making updates directly to the table.
The attachment itself doesn't have to be resaved, but I want the history table to show that a change have been made.

Hope someone can help me

Ok, after doing some more testing it seems as the attachment field do trigger the update macros but the field in the history table cannot be accessed from the macro since it is of type attachment.

So I will change the history field to some other data type, however I still need to read some unique information from the original tables attachment field (for example the file name), any ideas?
