+Summary: TextBox: much truncation, width measuring wrong?
+
+Repro is ./ch02_Forms/VisualInheritanceSample from the sample code for 
+the book "Windows Forms 2.0 Programming," by Chris Sells and Michael 
+Weinhardt, sources available from 
+http://www.sellsbrothers.com/writing/wfbook/
+
+Tested and found on SVN head Win32, 1.2.5_5 Win32, 1.2.4 Win32.  
+Behaviour is apparently good on 1.2.3 Win32.  Behaviour is good on 
+1.2.5_5 Suse VM.
+
+I'm hoping that this is some artifact of my machine, I presume someone 
+else would have seen it previously.  I guess it's only on Win32 so not on 
+the core platform...
+
+The text is "The quick brown fox, blah, blah, blah..."
+
+Run the sample and leave the text selected (ie blue background).  See the 
+following:
+1. The text is truncated on startup -- but textbox is dock filled!  I see 
+the truncation at "...blah, blah, bl".  See screenshot.
+2. Widen/Maximize window -- no change.
+3. Narrow the window to cause the text to wrap -- so the edge is just 
+after the second 'blah'.  See the end of the text (ending "blah..."), but 
+is still truncated at end of the first line.
+4. Take focus away (to another window not covering the window).  See blue 
+background disappear.  See all the text appear.
+5. Bring focus back, see again blue selection and truncation on first 
+line again.
+
+Restart app.
+1. Click right-arrow or END key to move cursor to the end of the line and 
+drop "selection".  Still see it truncated.
+2. Widen or even narrow slightly the window -- all text appears.
+3. Note that cursor is at the wrong position: enter some text 
+e.g. "aaaa", note that it is added at the 'real' end!  The cursor is 
+obviously drawn at the wrong position.
+4. Use the arrow keys to select to the beginning of the text.  See both 
+black and white text being drawn and merged. Yuk.  See screenshot.
