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: 
It's definitely the external links that are the issue. The culprit in my case was a font file also being loaded from Google.

**Problem:**

```
<link rel="stylesheet" type="text/css" href="http://fonts.googleapis.com/css?family=Reenie+Beanie">

```

Commenting or removing this line does work, but the problem is that I need this font to test the website as I'm developing. What I did instead (since I'm using PHP) was echo out the link so that DW can't try to crawl it.

**Solution:**

```
<link rel="stylesheet" type="text/css" href="<?php echo "http://fonts.googleapis.com/css?family=Reenie+Beanie"; ?>">

```

It's pointless code, but it works - DW will stop hanging and the font will still work when testing in a live environment.
**FIX FOR ME IN LOCAL CSS FILE:** I had to right click on each file and try to "Edit with Dreamweaver" until I found the one that really was behind the crashing on start up. I got the crash on index and a specifc css file (local).

I;m using Bootstrap 3. Works fine on my laptop running wamp, but not on my main PC using IIS7. I tried all the other registry cleaning and cache cleaning techniques, but no go until I removed this one piece of code from the local css file.

Hope it helps someone else.

This I removed this section of a css file:

```
@media (min-width: @screen-sm-min) { 
    .featured-box{
        margin-top:5px;
    }
}

```
