Lectora menu under Vista not responding

The way the menu system is implemented in Lectora seems to expose a bug in the HP/Dell Vista Video drivers. It causes Lectora to become unresponsive along with greatly slowing down the OS when clicking on the main menu. To get around this problem, until HP/Dell releases a driver update, the user will have to turn off a couple of the visual special effects in the Windows Vista OS. To do this:Click Start, right click on "Computer", and click Properties. Chose "Advanced System Settings" and on the "Advanced" tab, click the "Settings" button under the "Performance" section. Go to the "Visual Effects" tab; Uncheck these options: Fade or slide menus into viewUse visual styles on windows and buttonsClose the Performance Options & System Properties dialogs.
