Hi,

Has anyone experience any problems with Internet Explorer hanging when using Intersoft controls?


I've had this problem a number of times and I'm wondering if it is to do with the intersoft controls or nesting of these contols.


At the master page level I have a WebPaneManager that has three areas: 

  1. A top menu bar and toolbar.
  2. A left menu bar
  3. A content area
This UI is to mimic the Outlook style UI.  In some content pages I have other WebPaneMangers nested to further sub divide the screen and various other controls like grids, toolbars etc.

This problem first occured in the WebUI 2008 SP2 where I had the content area vertically divided in two, each verical pane contain a single user control.  Each Usercontrol used another WebPaneManger which horizontally split its space to allow for a toolbar area and a content area.

The Usercontrol on the left side of the vertical split contained a Toolbar and a WebTreeView control, the Usercontrol on the right contain a ToolBar and a WebGrid.

This UI design works well but every so often after about 30 mins or more Internet Explorer would just hang and consume about 50% of the CPU and very erratically consume up 300 MB or memory.  The only way to resolve the problem was to kill IE.

I redesigned the page using HTML tables rather than the WebPaneManger which seems to have fixed the problem.

However since I've upgraded to WebUI Studio 2009 I am getting random IE "hangs" on other pages previously unaffected.

Any ideas?

Regards,
Adrian.
