[imp] Notice: Undefined Index in view.php on line 37

[Binderhofer Thomas]

with my imp installations it's not possible to download attachments by
clicking on the disk picture and also it's not possible to save whole
mails to local disk

this is the error message for both: "Notice: Undefined Index in view.php
on line 37"

Line 37: $mime = $attachments[Horde::GetFormData('id')];

any idea ?

thx thomas
