IE7 - Random Freezing / Lockups

[Timothy]

Hello,

Does the RAD Window have some issues with IE7 when using the radconfirm / alert functionality?  On your examples website, the demo for these causes my browser to randomly lock up.

http://www.telerik.com/DEMOS/ASPNET/Prometheus/Window/Examples/BrowserDialogBoxes/DefaultCS.aspx

For whatever reason if I click around enough eventually it will cause the browser to stick and when I look in task manager I see the browser sitting at a constant 50% CPU usage.

I didn't notice this though until I had integrated it into our application.  It is happening there as well which leads me to believe its not an issue with the demo but with the actual control.

Sometimes I won't get it until clicking through your demo for a minute or two but eventually it does show up and I have no other option then to ctl+alt+del.

Either my IE7 installation is broken (which I very much doubt) or your control is.

Hi,

Has this bug been fixed yet in Q2 2008?
The version of the RadWindowManager is 2008.2.723.20, visible in VS.

(i can reproduce the problem at your example website)

Thanks in advance.

Hi Egbert,

The problem still exists. We are working on it and once we find a fix, we will update the control.

i have the same problem when I open a radwindow within a radwindow
on some computers, not all computers. What gives the difference. We use the same IE 7 browser, with all updates installed. Tested on 4 computers and only one has the freezing problem.

Waiting for the solution

Hi Herman,

The problem itself is very strange and unfortunately so far we are not able to track it down to a specific reason. Can you please check if your computers have the exact same version of IE and JavaScript engine? This could help us in the investigation.

Hello, Georgi:

What is the latest with this issue? Is there a solution ? We are unable to use radconfirm/radalert  due to problem with IE. It seams to be working OK in Firefox. Any info is appreciated.

Hello Craig,

Could you please tell me are you using the latest version? Do you get the same error on our online demos?

I am asking you this because in the last year we made same changes to the dialogs and currently I cannot reproduce the problem anymore. If you experience problems on your side with the latest version, it will be best to send us a sample project along with reproduction details. We will check it and do our best to help.

Georgi,

I do not get the error with the online demos.  

I am ruinning Q1 2008  and I am trying to upgrade to Q3 2008 (2008.03.1314.20).  However, when I copy the new Dll to my web server, I am getting an error: 
Conversion from type 'List(Of ScriptEntry)' to type 'Boolean' is not valid.   It is a DotNetNuke site and the stack trace is below.  

As soon as I replace the old dll Version (2008.1.619.20)  everything is fine.

I resolved the upgrade problem and the IE freezing problem went away.

FYI  The issue is the the steps to replace the default Script Manager in DNN.  They are still wrong on the Telerik site saying to replace ALL occurances of the system with telerik.  I found a forum post which said this is not correct and only one item should be changed.
