Hyperlink to SSRS Report throws JavaScript Error

Question

Hoping this is the right place to get help here. I'm not sure if this is an error in ASP.NET, SQL Server 2005 Reporting Services or some compatibility issue between VS 2010 and VS 2013 Express for Web.
I have an ASP.NET web form written in VS 2010 / VB.NET. The form has three hyperlink controls that have NavigateURL properties that are set at runtime. Those URLs point to reports on a SQL Server 2005 Reporting Server. The app runs in our Intranet and we use
Windows authentication throughout. I am using the ASP.NET Development Server (Version 4.0.30319.18408) locally.
This app used to work just fine, but recently it broke. Now when I run my code and click the hyperlink control (IE is the default browser) I get a JavaScript error of monumental complexity/density.
The URLs work in IE. They work in FireFox. If I set FireFox to be my default browser it's opens fine from VS. But when I run it in IE I get the error. 
When I click the Hyperlink, I get a messagebox saying "Javascript runtime error. Access is Denied." [Break] [Continue] [ Ignore] 
Behind that, in Visual Studio, there's a 'Script Block [dynamic] tab open. It has a lock symbol on it and the window is FILLED with hugely dense and incomprehensible Javascript.  If I break, I'm dropped into the code. The offending line is:
this.FieldFocus=function(a){var b="undefined"!=typeof LP?LP.getBrowser().selectedTab.linkedBrowser:null;if("undefined"==typeof LP||b){var c=b?b.contentDocument:document;if(c&&!("undefined"!=typeof c.FieldFocusDone&&!0==c.FieldFocusDone))if("undefined"!=typeof
c.LPlpUseLastPassLogin&&!0==c.LPlpUseLastPassLogin)lploggedin?(c.LPlpUseLastPassLogin=!1,LP.FieldFocus(a)):(lp_showNotification("UseLastPassLogin",b,0,"login",null),c.LPlpUseLastPassLogin=!1,c.LPlpm_setupFocusHandler=!1,c.FieldFocusDone=!1);
else{if(lpNotificationsAfterClick)lpCheckGenPwAndFF(b,c,!1);else if("undefined"==typeof c.LPlpgenerateandfill&&"undefined"!=typeof c.LPlpfillforms)lp_showNotification("FillableFormDetected",b,0,"formfill");else
if("undefined"!=typeof c.LPlpgenerateandfill)lp_showNotification("GeneratePassword",b,c.LPlpgenerateAids,"generate",c.LPlpgenerateForm,null,c.LPlpgenerateandfill,c.LPlpfillcurrent);else return;c.FieldFocusDone=!0}}};
Needless to say, I have no frickin' clue what this is. I'm new to web programming, so this is totally beyond my abilities. 
Possible Factors:
Compatibility view is on for all Intranet sites, but turning that off makes no difference.
I recently upgraded from WinXP to Win7 64-bit. 
I also recently tried loading the Web Project into VS 2013 Express. 
I'm not sure which of these may be a factor, just thought I'd mention them.
Fix Attempts:
I tried removing my fancy code and just setting the correct URL in code. Error.
I created another hyperlink control, and in code I copied NavigateURL from the existing control to this one. Clicking that one WORKS. WTH?
Any help would be deeply appreciated, thanks.

Well you can post a question in the ASP .Net forum and see if you can get an answer.
"The URLs work in IE. They work in FireFox. If I set FireFox to be my default browser it's opens fine from VS. But when I run it in IE I get the error. "
The above makes no sense to me. The URLs work in IE but when I run it in IE I get the error?
This makes no sense either "This app used to work just fine, but recently it broke" as apps don't just break. Something changes to cause an issue with them. Which systems did the app "break" on? What upgrades were recently done on those
systems?
When you opened the project in Visual Studio Express 2013 for web is that when the app broke? Maybe the app requires more than Visual Studio 2013 Express for web has available.
Was Visual Studio 2010 an Express edition for web? Or did it have more capability than that?
Did you load a newer version of IE on that system? As the WebBrowser control, from what I understand, uses the current rev of IE on the system as "The
WebBrowser control is a managed wrapper around a component installed with Internet Explorer. Use this property to determine which version of Internet
Explorer is installed. This is useful when your application uses a feature of Internet Explorer that is present only in certain versions. If the required version is not present on the local machine, you can provide alternative functionality or prompt the user
to upgrade". Maybe something there occured. Or do you use the WebBrowser control?
Is Visual Studio 2010 on the Win 7 64 bit machine? If so does that app not work in that too?
Did you compile the app to AnyCPU rather than X86 or X64 or try to compile it to one of the other two to see if that corrected the issue?
There's obviously something going on which you've not taken into account from a to b.
Please BEWARE that I have NO EXPERIENCE and NO EXPERTISE and probably onset of DEMENTIA which may affect my answers! Also, I've been told by an expert, that when you post an image it clutters up the thread and mysteriously, over time, the link to the image
will somehow become "unstable" or something to that effect. :) I can only surmise that is due to Global Warming of the threads.
