Sorry for the delay, I was real busy...

Here is a fix to use from within the thread (Administative)

Edit threadadmin_deletethread

Look for:

<input type="checkbox" name="keepattachments" value="1" id="cb_keepattachments" tabindex="1" /> {vb:rawphrase keep_attachments}

Replace with:

<input type="checkbox" name="keepattachments" value="1" id="cb_keepattachments" checked="checked" tabindex="1" /> {vb:rawphrase keep_attachments}
