Prior to this release, when using the Advanced Mime Editor within a subsignature, pressing the "reload" button would result in the following error message.
There is no MIMECONVERT document for key 'Subsig-', please resave the configuration document to re-create the MIMECONVERT document.
This is only required if you wish to "start again" from when the sub signatures was first opened. This can still be achieved with closing the sub-signature and re-opning.
This issue was resolved in V4.02.
