I closed the settings window. How do I get it back?
Use the dock menu (click and hold the Mouseposé icon in the dock), the status item in the menu bar or Settings… from the Mouseposé Windows menu (Command-O).
I hit the hot key and I get gray controls on the screen instead.
This only leaves you a few other keys to assign. However on Laptops you can use any function with a system control for Mouseposé together with the fn-key (lower left corner of your keyboard). Use the Keyboard & Mouse preference pane to toggle this behaviour.
I hit the hot key and the windows all move around instead.
You have chosen one of the Exposé hot keys instead. These system settings override Mouseposé hot key assignments. By default the F9, F10 and F11 key activate different Exposé functions. You can check your settings in the Exposé preference pane. Choose a different function key, which is not used by Exposé.
Mouseposé is not reacting to the hot key. What is wrong?
(1) The Mouseposé application is not running. If there is no Mouseposé icon in the Dock or no small black triangle next to the Mouseposé icon in the Dock, it is not running. Click on the icon in the Dock or locate the Mouseposé application and double click it to start. You might want to activate the "Automatically start Mouseposé at login" option to have it running after login.
(2) You have chosen a combination of opacity and color that is hardly visible when activated. Choose a different color and opacity setting or press the "Revert to Defaults" button to change to the standard settings.
Mouseposé does not work during Keynote Presentations. What is wrong?
Nothing is wrong. When Keynote starts the presentation it puts up a "protected screen". This is a feature of Mac OS X that prohibits any other application to draw on the screen, as long as Keynote has control. If you want to change this behaviour, open Keynote's preferences, navigate to the tab Slideshow and check the option Allow Exposé, Dashboard and others to use screen. You will then be able to use Mouseposé during your Keynote presentation.
Note: This feature only works with Keynote 3 and later.
Note: Microsoft PowerPoint does not seem to set up a protected screen, so Mouseposé will work during PowerPoint presentations.
