+Summary: Inserting text into existing (selected) text in a TextBox sometimes throws an ArgumentOutOfRangeException
+
+This bug is hard to reproduce.
+
+Sometimes, if I insert text into (selected) text in a TextBox I get an 
+System.ArgumentOutOfRangeException.
+As I wrote before, it is hard to reproduce. Best would be to use wordpad,
+write some text, select it, set char size to 72 and start inserting text
+(really fast).
+
+This is the exception:
+
+Unhandled Exception: System.ArgumentOutOfRangeException: Argument is out of
+range.
