Hierarchical tree node problem

Question

Hi all --
Today's problem is (drum roll)............
My application uses a heirarichal tree where each tree node contains the name of a form within this system. The user can navigate from form to form by clicking the appropriatetly name tree node. This seems to work - sometimes. Some users click on a node for one form, but get transferred to another named form(usually the one above or below the one actually activated). I've also found out that this happens ONLY when the user has their screen resolution set to 800 x 600. This application was developed at screen resolution 1024 x 768 and it woks fine. Anybody know why??

Here is the code for both the tree node selected and tree node activated triggers
Tree Node Seleceted code:
:CONTROL.Node_Activated := null ;
:CONTROL.Node_Selected := Ftree.Get_Tree_Node_Property('CONTROL_TREE.MENU', :SYSTEM.TRIGGER_NODE, Ftree.NODE_VALUE) ;
===========================================================
Tree Node Activated code:
Declare
LN$I Pls_integer ;
Begin
:CONTROL.Node_Selected := null;
:CONTROL.Node_Activated := Ftree.Get_Tree_Node_Property('CONTROL_TREE.MENU', :SYSTEM.TRIGGER_NODE, Ftree.NODE_VALUE) ;
If :CONTROL.Node_Activated IS NOT NULL Then
if :GLOBAL.curr_proc_id <> :control.node_activated or :control.node_activated
is null then                          
CALL_FORM(:CONTROL.Node_Activated);     
else
Set_Alert_Property( 'AL_FORM_OPENED', ALERT_MESSAGE_TEXT,
:CONTROL.Node_Activated || ' is already opened. Please check your current or previously opened library.' );
LN$I := Show_Alert( 'AL_FORM_OPENED' ) ;
end if;          
end if ;
end ;
