First, I will say, I do have a work around for this as gathered from previous threads
here: http://www.telerik.com/community/forums/aspnet-ajax/combobox/radcombobox-scrolling-selection-locks-browser.aspx
and here: http://www.telerik.com/community/forums/aspnet-ajax/combobox/radcombobox-ie-7-freeze-problem.aspx
But I wanted to post again because this didn't happen for us until we upgraded to the 2010 Q2 release so this is still an issue.
Description:
I have multiple RadComboBoxes (RCB) in a RadWindow that pops up, and all the RCB have mostly the same property settings.
When I click one of the RCB, it opens and the whole browser freezes as the CPU is maxed.
If the RCB in question has fewer items in it (so that it doesn't extend passed the RadWindow boundries) there's no problem. This is odd because the first few RCB are fine, including one that has enough items to extend passed the RadWindow boundries.
Solutions (from the links above):
Either set the RCB property EnableScreenBoundaryDetection="false" or set the RCB property MaxHeight to some number that will keep the list from extending past the RadWindow boundry.
Just wondering if there is some kind of fix coming to avoid doing these workarounds whenever they crop up.

Hi Robert Helm,
It is not good that this bug has come back into existence. Perhaps it is another case which we have missed to cover.
Can you open a support ticket and send us a project showing the issue there? We will immediately investigate it and will provide you with a workaround.
Best wishes,
Simon

Thanks Simon,
If I can, I will submit a support ticket with an attached example project.
However, for now I already have a workaround, just set EnableScreenBoundaryDetection="false" or set MaxHeight to some appropriate number.
I'd like to add that the popup RadWindow that contains the RadComboBoxes has AutoSize="true" so it seems like the RadWindow is might be trying to resize while the RCB is trying to detect the screen boundary of the RadWindow.
Thanks.

We're seeing this behavior too. Our situation:
* Window is a chromeless window opened using javascript window.open
* RadComboBoxes are populated via web service after 3 characters are entered
* Browser (IE8, Windows XP) locks up after data is retrieved from web service (but only when more than a few results are returned). This may be the point where it would need to draw the dropdown larger than the window can contain.
The above mentioned workaround works in this case as well. We are on 2010 Q2, but haven't moved to SP1 yet.

Hi. I'd just like to add that I too have come accross this bug. It happens to me in XP SP3 with IE7 and Win7 with IE8. For me, setting the EnableScreenBoundaryDetection="false" seemed to fix the problem for me. I have only seen this problem with a large list (about 1000 items) in the radcombobox inside a radwindow. I'm using version 2010.2.713.35. Hope this helps. Thanks.

I've had this happen before. However, my radcombobox is not inside a window, just on a page. Freezes IE and everything.
Happens intermittently on some people's computers. Hopefully the suggestions above will fix it

This issue exists after I upgraded to the latest version. radcombobox locks ie11. None of the remedies suggested here work, i.e., maxHeight="200px" or EnableScreenBoundaryDetection="false".

Ivan, please see http://www.telerik.com/forums/radcombobox-scrolling-selection-locks-browser#BNtQvYozXkefaqg4VSMJ_A
Andrew sent a sample project and Telerik was unable to reproduce the issue on their side. Since Telerik can't reproduce, why don't you send me Andrews sample project and I'll run it in my environment.

Hello bigred,
I replied to the ticket submitted with the same subject in the ticketing system. In order to avoid thread duplication I suggest we continue the discussion there.

I had the same issue, and I have resolved only to set RenderMode="Lightweight" in the RadComboBox.

Thanks, I already fixed the issue by removing the meta tags that were forcing the page to run in IE8 compatibility mode.
