Hi
Attention: THIS IS NOT FOR COMMIT!!
As Attachment the Testdiff file ( working fine on Windows XP .NET SP2 but
not on mono cygwin)
And the current GetCharFromPoint in TextBoxBase.diff
Hope this helps
Yours

Yes, fonts will be different between different machines. You can't rely
on the user having the same size font on every machine. What you should
do, is explicitly set the font size for the textbox in your tests.
Do you mind sending your tests to the list? It's hard for me to tell
exactly what is going on from the test output, without seeing the tests.
