[Wine] mouse pointer disappears in the window of apps under win

[guy_c]

Hello, I am just starting to use Wine

Simplest example: under Ubuntu Application > Wine > Configure Wine: The Wine Configuration window comes up. If I move the mouse into the window (tabs or anywhere except the top title "Wine Configuration") the mouse pointer disappears.

Wine > Program > Accessories > Notepad: no way to see the pointer if the mouse is moved beneath the "Untitled - Notepad" strip

My system: Ubunto 9.10, Compaq Armada 1750 laptop, 320MB

Thanks in advance
