Thanks for the report. I think that at the root this is the same bug 
that others were encountering with Scintilla event handlers, which is 
now fixed in SVN. I will try and reproduce using the ListCtrl on Windows 
(the bug depends partly on how the OS allocates memory blocks).

Useful to know that it wasn't a problem in 1.9.8 - will check see if any 
other classes might have this problem. It will be fixed for 2.0
