Sorry to say but 1.7 worked fine on my Droid and 1.8 is crashing immediately upon load.
The application Trackmaster (process com.trackaroo.apps.mobile.android.Trackmaster) has stopped unexpectedly. Please try again.
This is after a restart. After I first did the update it would load but just turn the screen black after the splash. Subsequent restarts result in the same immediate crash.
