Hi MonsieurLeblanc,
Did your trackpad become unresponsive only once when waking from sleep, or is this a persistent issue? Below are some troubleshooting steps you can try if it happens again. If the issue is not resolved, you may wish to have your MacBook Air physically inspected by a Genius at an Apple Store or by one of our Authorized Service Providers.

Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
http://support.apple.com/en-us/HT201295
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
- Shut down the computer.
- Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
- On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
- Release all the keys and the power button at the same time.
- Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
OS X Mavericks: Reset your computer’s PRAM
http://support.apple.com/kb/ph14222
A small amount of your computer’s memory, called “parameter random-access memory” or PRAM, stores certain settings in a location that OS X can access quickly. The particular settings that are stored depend on your type of Mac and the types of devices connected to it. The settings include your designated startup disk, display resolution, speaker volume, and other information.
Note: To print these instructions, open Help Viewer’s Action pop-up menu (looks like a gear), then choose Print.
- Shut down your Mac.
- Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step 4.
- Turn on your Mac.
- Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the gray screen appears.
Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.
- Release the keys.
Resetting PRAM may change some system settings and preferences. Use System Preferences to restore your settings.
