Thanks for the reply. Here is the sequence.
Create a new .aspx page.
Place an ASPxRoundPanel onto the form. I leave all of the defaults after the control is created.
I place my cursor in the content area of the ASPXRound Panel and then I double click the WebChartControl in the toolbar.
I then run the wizard to set up the graph parameters and the series information.
After I exit the wizard, the environment locks up. I have to reset the VS2008 environment and/or reboot the machine.
When I attempt to load the page back into the design environment, the environment locks up.
I can place an ASPxRoundPanel and a webchart on the same page (but not having the chart inside the panel) and everything works fine.
I also tried the following. I created a new page. In the graphical environment, I dropped a round panel and added some content. I then switched to the source view and double clicked the webchartcontrol to add it to the content section of the round panel. When I attempted to switch back to the graphical design view, the system locked.
I have tested this on two different development environments and I get the same result. It looks like when the chart control is trying to write to the source file, it gets confused and locks up.
