Loosely Coupled IE (LCIE) sounds good but somehow cause an issue with Visual Studio .NET 2003 in debugging mode.

Have to test if this solves the sporadic crashes like this (even with add-ons disabled):

about my problem

re: Opening a New Tab may launch a New Process with Internet Explorer 8.0

I use IE8 with Windows XP. I have a real performance problem when I click on a hyperlink, open or close Tabs. The CPU usage goes to 100% and the explorer.exe and the multiple iexplore.exe processes (usually 4 or 5) all start using CPU. They are all at 00, but will quickly jump to a combined total of 100 if I click on a hyperlink. It takes sometimes 3-5 minutes to open the hyperlink in a new Tab. Additionally, they jump when a Tab is closed and stay at 100 for about 40 seconds; similarly jump to 100 when a Tab is closed for 50 seconds. Right now I have 6 Tabs in 2 windows with 5 instances of iexplore.exe running. Turning off add-ons had no effect. I would appreciate your help on this.

Visual Studio .NET 2003 and Visual Studio .NET 2005 have the same problem.

try the following..

In the RegisterKey go to

HKCU\Software\Microsoft\Internet Explorer\Main

ADD DWORD with the name TabProcGrowth and set the value to 0

Apparently IE8 doesn't support "run as" that is to say running IE8 as another user, without having TabProcGrowth set to 0.

I would prefer to be able to separate my browsers and run them under different user accounts without having to keep using fast user switching. BTW would also be nice if I could have them use different colour schemes for the titlebars etc.

This way I can have one browser instance for banking, and another for my regular sites, and yet another browser instance for less trusted sites.

As it is, I am sticking with IE6 because it seems IE8 does not support this well.

Might be just coincidence but I've experienced two XP computers that had IE7, and for some reason fast user switching often does stops working on them (can't enter password - have to use ctrl-alt-del as workaround). So I'm sticking to keeping my "old" stuff patched and not moving to the new stuff yet.

Ah the "can't enter password" problem I was talking about was this one:

No fix even after 3 years though (people have been complaining about it for years).

An unpleasant side effect of this innovation is that older versions of Developer's Studio do not attach a debugging process to the browser. Setting dword TabProcGrowth to 0 fixes it, however (1) this information is somehow hidden from developers (I had to do a web search; found a solution at http://weblogs.asp.net/abdullaabdelhaq/archive/2009/06/01/VS-Debug-Problem-with-IE8.aspx); (2) this change affects the behavior of all instances of the browser, not just the one that the debugger is working with.

"Loosely Coupled", I struggle to find something positive to say about IE 8. I am a Microsoft kinda guy. I've been with you guys since NT 3.51. SharePoint MCTS etc. IE 8 is just not stable. It crashes when I get more than a handfull of tabs open. With Firefox I never have trouble. Why is it that IE 8 can't handle more tabs. I am on a dual proc PC with 3 gigs of ram and just Onenote and Outlook running. Even when I close those two down it still gives me fits. Very hard to work when I am researching through tech articles and trying to find answers.

I do agree with Keith Caravelli. If i have only one instance of IE open, with a few (3) tabs and i open another tab IE8 crashes. It's very anoying when i am making a service call for a customer and i have to open a new tab and IE crashes... i am all my text in the service call is lost

Note: On Terminal Server, the default value is the integer of 1 for TabProcGrowth is incorrect.

On a windows w2k3 sp2 system fully patched till november 2009 IE8 still creates an extra process. The value does not exist. After creating the value it does function correctly.
