By using the WinNewAt function with parameter
"128 - Open a unique window.
This mode prevents this window from being opened more than once".

However, in v7.0, it is still possible to open the popup windows several times.  


The function call must contain the cluster name.
The optional parameter "cluster name" must be declared, else we get the bad bahaviour.

Citect has confirmed this to be a problem in CitectSCADA version 7.00. This issue will be fixed in a future release of the product.

In the case of CSV_MM_WinNewAt there is no optional Cluster definition. In this case the page name can be prefixed with the Cluster name: "CLUSTER.PAGE"
