Internet Explorer 7 freezes and becomes unresponsive

We have encountered a peculiar issue in our asp.net 2.0 web application involving a user control with validation. When the validation fails, the visual appearance of the page remains unaffected, yet no controls such as buttons, scroll bars, or third-party components like Telerik text editor respond to mouse inputs. Strangely, resizing the browser window seems to temporarily restore the responsiveness of the UI. Has anyone experienced a similar problem before? What might be causing this unusual behavior?

Answer №1

Is this occurring in different browsers as well? Are you referring to validation on the client side or server side (specifically, is there a post back)? Have you attempted removing all CSS to determine if the issue persists? If not, gradually reintroduce the CSS elements until the problem resurfaces to pinpoint the cause!

Answer №2

Make sure to review your CSS and javascript for any potential issues. It appears that there may be an invisible element (such as a div) covering the elements on the page.

Answer №3

In my experience, Internet Explorer has a tendency to freeze when resizing if there are CSS expressions present.

#wrapper{
    width: expression(document.body.clientWidth > 1100)? "1100px" : "auto";
}

It's not uncommon to find yourself in a situation where two elements are resizing based on each other, potentially causing an endless loop that can lock up the browser. Additionally, it's worth noting that expressions will no longer be supported in IE8 standards mode, so it's best to remove them altogether.
