Question: I want to implement layering of screens when transitioning from one screen to another.

Requirement:

i> There is a screen with a button.

ii> When the user clicks on the button , the next screen is displayed in the following manner.

It should move up from down & place on top of the existing screen.
On iPhone , technically its known as implementing the **present model view controller**

I am aware of moving screens left & right , but is there already available API for implementing what I have mentioned.

Any inputs/sample code for implementing the same will be useful.

Warm Regards,

CB

Answer: 
Dreamweaver CS5 definitely has issues with externally sourced items. I just got the same type of failure when trying to include jquery from googleapi:

```
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.0/jquery.min.js"></script>

```

Removing the line or commenting it out allows Dreamweaver to open and work with the file.
Great, this post helped me solve my problems of crashed on a specific file in Dreamweaver CS5.
It's indeed the external font that crashes DW.

I found an easy fix, omit the protocol part and it works:

```
<link href="//fonts.googleapis.com/css?family=Open+Sans:400,700" rel="stylesheet" type="text/css">

```

and **NOT**

```
<link href="http//fonts.googleapis.com/css?family=Open+Sans:400,700" rel="stylesheet" type="text/css">

```
