Is there a maximum data size for groups?

[Jonathan Lynch]

Both in Rev 3.5 and Rev 4.0 I have a problem trying to copy a group from one
stack to another. The group contains approximately 400 mb of information
(mostly images). This problem seems to arise whether I copy the whole group,
or copy it piecemeal into the recipient group.

So, do you guys know if there is a built-in limitation on the data size for
single groups?
