.Net 2.0 TreeView Performance is killing NCoverExplorer

If you are familiar with the Windows Forms TreeView control, please take a look at Grant Drake's post on performance issues under .NET 2.0. You will find example code and a graph comparing its performance under .NET 1.1 and .NET 2.0.

It is upsetting to see the otherwise snappy NCoverExplorer turn into treacle when only .NET 2.0 is loaded (.NET 1.1 has precedence in the 'App.config' file). If you can find a solution, please let Grant know!
