Window opening in slow motion

Well, it may not be slow - not sure how to measure such a thing but it looks pretty bad.

I have a Search file and a Customers file. The Search file displays three portals to display found Customers, Prospects, and Associates. Yes I know, they should be together (and they will be) but for now, this needs to function. The Customers file has three portals of Products, Invoices and LineItems. After people are done in Customers, they can click Search and it takes them back to the Search file menu. This works fine as it a simple Close File.

But when they click the portal row in Search to jump to the Customer file, the Customer file opens from the bottom right upwards to the top left - kinda slow - and flashes and (I swear) I can see another file/layout under it as it switches - probably Search. Could everyone check my scripts and see if I can fine-tune it to keep it from being so obvious?

Search File/Go To Related Customer script:

Set Field [ gGoToCustKey, Cust::CustID ]

Go to Related Record [ Customers ]

[ Show only related records ]

Perform Script [ Filename: "Customers.fp5", "Display Customer" ]

[ Sub-scripts ]

Customer File/Display Customer script:

Go To Layout [CustomerMenu]

Set Field [gInvoiceNo, ""]

I have tried adding Freeze Window[] at the start of both these scripts but it didn't seem to help. Anything else I can do to make the switch more seamless? Thanks for helping me.
