This issue is found in Flex 3 beta 3 and was working fine in
Steps to reproduce:
1. We are working on big application and in some cases we
have nested containers. Inside the nested containers we have
Advanced DataGrid or Line Charts with slider. Nested Containers
have been upto 15-20 level deep nesting in few cases.
Example: (when traversed from multiple MXML)
When DataGrid appear on the screen and I click on the Header
of the DataGrid. It seems to hang for sometime. This issue is found
in beta 3 and was not available in beta 2.
Workaround (if any):
I have reduced the number of nested containers and then it
is working fine but it's not possible to reduce for all. So,
looking for suggestion.
