Runnig Windows XP and have a reference to Excel 10 in C#. Have modified the
Interop.Excel.dll to handle excel events in C# using KB article 316653. After
making the "_SinkHelper" classes public I have the following problem:
Starting Excel from C# the application area of Excel showing the worksheet
itself is transparent and it is not possible to see any part of a worksheet.
Starting excel the normal way everything looks fine.
What has happened? Do I need to make any additional settings?

Any help appreciated.
