I have a custom webpart in SharePoint WSS 3.0 which only contains a WARP panel. The WARP panel
contains a button and a button click event handler is set to do System.Threading.Thread.Sleep(3000).
When the webpart is first loaded on initial page load and I click on the button, no progress indicator
shows up. When I click it the 2nd time and onward, the progress indicator will then show up.
The WARP panel and the button are added dynamically at runtime inside CreateChildControls method.
I appreciate any advice on this.
