PD9 on Mavericks with XP Home SP3. Using a program called Taxcalc with MacLook enabled, many of the check boxes do not show their state. Although the underlying program knows whether the check box is set, the tick is not visible. Problem persists with either Full Screen and Coherence as well as windowed. Also, in Coherence, the cursor is displaced such that I need to click with the cursor above a button to activate the button.
