Error with onclick in Panel & Internet Explorer/Mozilla

Hi Experts,

I created a Design Studio Application with Version 1.2 and tried now the latest Version 1.6 SP3.

So far everything is working fine I just have one issue with onclick events and Panels.

Until know it was possible to have a structure like following:

PANEL_1_MAIN

     - PANEL_2_HEADER

     - PANEL_3_BODY

and i was able to create a script behind the PANEL_1_MAIN onclick event.

So everytime someone click anywhere in the PANEL_1_MAIN Panel the script was executed.

Now with Version 1.3 SP3 it seems that the script is NOT executed anymore if you click on the PANEL_2/3 within the PANEL_1_MAIN.

Nevertheless the correct "click" mouse pointer is shown, but nothing happens.

With Chrome everything is working still as expected, but IE is the main browser used in the company.

So hopefully someone can help,

thank,

andreas
