I just upgraded the XP-32 bit 2.2.2 version with 3.0.6 32 bit. Now the control panel no longer appears after I double-click the left button to go full screen. Also the cursor immediately vanishes. Normally I wiggle my rodent and the cursor would appear as well as the control panel on the bottom of the screen. Now neither appears. If I left click, the cursor will appear, but no control panel. The right-click still brings up the sub-menu. It is a little tough to click the next chapter button when the control panel isn't there.
So much for the installation keeping the preferences. How do I fix this?
Side note: I upgraded from 3.0.3 on the Win7-64 bit box and it works as expected. But it has a separate issue and a separate posting because of it.
