Using vs2008, winforms C#.

Im using the crystal reports version that comes with vs2008.

I can create and load a crystal report ok. But becasue it can take a few minutes to load, i want to bring up a wait cursor, but am having trouble with that.

I have tried setting the this.crystalReportViewer1.Cursor = Cursors.WaitCursor;

and tried the parent form this.cursor = cursors.waitcursor;

The cursor changes briefly to wait mode, then changes back before the report has finished loading. How can i best set the wait cursor before the report starts to load, force it to stay in wait mode then change it back to the arrow, only after the report has finished loading

thanks for any advice
