The character drawing 'brush' tool in Wenlin 3.3.6 now works 'as expected' in CrossOver 6.1.0!
In previous versions of CrossOver, and also versions of WINE that I have tried, the brush stroke does not appear until the the stroke is completed, either by releasing the left mouse button (if you are using a mouse), or you lift the stylus off the tablet (if you are using a Wacom tablet). Now you can see the stroke being drawn on the brush tool when it is actually being drawn.
Cutting and pasting from a Linux application into WenLin still requires the workaround as described in the Tips & Tricks section.
Great job, CrossOver/WINE team!
