Really Simple security problem i hope

Hi,

I am using the following to display a view in a tab

<apex:page >
<apex:enhancedList listId="00B20000006X0Le" height="600" customizable="false" rowsPerPage="25"/>
</apex:page>

I have set the profile so the VF page is enabled for it but when i am logged in as the standard user i am getting the following error

Insufficient Privileges
You do not have the level of access necessary to perform the operation you requested. Please contact the owner of the record or your administrator if access is necessary.

I have also noticed that i set the VF page access when using sys admin, then wheni log in as a standard user and look at the profile page the enabled VF page access panel is blank.

Thanks for any help in advance
