+Summary: nunit-gui: crash when nagivating tests tree after loading and running 2 test assemblies
+
+Steps to reproduce the problem:  
+1.  run nunit-gui 2.2.7 
+2.  File->Open nunit.mocks.tests.dll 
+3.  click Run 
+(they should all pass -- green bar) 
+4. expand all the nodes in the tests tree 
+5. collapse all the nodes in the tests tree 
+6. File->Open nunit.uikit.tests.dll 
+7. click Run 
+(mono currently has failures in the TextBox tests, but that's a different 
+bug) 
+8. Click on the first error in the Errors and Failures tab 
+9. Click in the treeview to expand nodes 
+ 
+  
+Actual Results:  
+ The tests tree no longer shows selection. Looking at the name of the 
+selected node displayed, it is from the previous nunit.mocks.tests.dll 
+assembly! After clicking around a while, nunit-gui.exe crashes. 
+
