Brian,
There is no setting to turn the link to the full calendar off, but a quick fix would be to change the PHP code as follows:
Change line 234 of the display0.php file
from . . .
$dateHdr = "<button type='submit' title=\"{$xx['vws_view_full']}\">".makeD($dateD1,3)."</button>\n";to . . .
$dateHdr = "<button type='button'>".makeD($dateD1,3)."</button>\n";. . . delete line 229 to get rid of the text "for full calendar click month".
That's all.
In addition you could of course also delete all lines related to the form: Lines 230 - 233 and 238.
Update: A minute ago I've made this a setting in the mini calendar. If you upload the mini calendar (display0) from the LuxCal Displays page, you will have the updated version.
