+Summary: weird behaviors in Form.FormBorderStyle = .SizableToolWindow
+
+Form shows weird behavior when its FormBorderStyle =
+FormBorderStyle.SizableToolWindow.
+
+Run winforms/toolwindows and see what happens on SizableToolWindow.
+
+- Linux: cannot resize the form.
+
+
+Steps to reproduce the problem:
+1. Run winforms/toolwindows/swf-toolwindows.exe
+2. show the first form by clicking the button, and hide.
+3. Do the same. Now SizableToolWindow is shown.
+4. On Windows, try to move the window by drugging the caption bar.
+
+Actual Results:
+
+On Linux, the window is not sizable.
+
+On Windows, the following error happens when MouseUp happens.
+
+$ mono --debug swf-toolwindows.exe
+Mono System.Windows.Forms Assembly [$auto_build_revision$]
