Problem Description

Earlier today I established a template for my web page through dreamweaver, created a few pages from that template, and was using BrowserLab to preview these pages.  I noticed an issue that spanned all the pages with my horizontal navigation bar at the top of my page, so rather than fixing this issue on each page, I decided to (logically) fix the issue inside of my .DWT file and update my pages.

I fixed the issue, and then used the "Preview from Local Disk" option that's built-in to Dreamweaver to preview the fix I made to my .DWT file in the BrowserLab.

This worked fine until I closed the BrowserLab and then tried to preview my DWT file through IE using the normal "F12" method.  I was prompted to "Download this file" like I was trying to download my own .DWT file from my own computer.  The "dont ask me again" option was selected and I hit ok, and it took my back to Dreamweaver without showing me the preview of my page.  Now (even after restarts), anytime I press F12 to preview my DWT page in IE, It quickly opens IE, flashes the dialog to download the page, closes it just as fast as it opened (since "Don't Ask me this Again" was selected, and returns me to Dreamweaver with no preview.  Using CTRL+F12 to preview in Firefox works just fine, and previewing the .html files created from the DWT template works just fine as well in both Firefox & IE.  Seems my DWT file is now stuck in some sort of infinite bug-loop which only started after my apparently crazy idea: "Lets preview this template in BrowserLab!"

Steps to Recreate

The steps we should follow to reproduce your issue. Minimally include all the following:

1. The issue occurs everytime after the initial preview of a DWT file in the BrowserLab.  I am using Windows 7 Ultimate 64-bit and Internet Explorer 8.
2. Testing via Dreamweaver CS5 built-in BrowserLab functionality from the "Preview from Local Disk" option.
3. This is not a public facing HTML document, and the content is locked under NDA, but the only code I am using in the page is HTML and a single CSS style sheet to control the look/layout of the page.

Expected Results

I expected to preview my DWT file (which worked the first time but now seems to be "downloading" itself from my local disk and overwriting itself with the same file.

Actual Results

Worked for the first preview, but now flashes Internet Explorer and the download dialog box then returns me to Dreamweaver without a preview.

To recap, I can preview my DWT and HTML files in Firefox without issues, I dare not try the BrowserLab again for fear it may cause further bottlenecks for me during a deadline-heavy schedule in my production cycle.

Any information that can help me restore my ability to preview a .DWT file using "F12" (Internet Explorer as main browser) would be greatly appreciated.

-Thanks!
