Martin,
In such cases, a crash log from your device would be HUGELY valuable in helping us address these issues. Here's how to get one:
1. Check out and install this (free) app: Catlog - Logcat Reader!
2. Open the Chess app and do whatever is required to reproduce the crash/force-close
3. Then just open Catlog and select Menu > Save.
4. Now you can use Catlog's "Share" feature to send the log as an email attachment. For now, please send any logs to deepgreene@gmail.com
The newest version has been crashing every time I try to go in and try to do tactics. This happens on both of my devices.
Talblet: Asus TF101 with Android 4.0.3
Phone: Samsung Nexus S with Android 4.0.4
I have uninstalled and reinstalled on the tablet and the problem persists. Anyone else having issues?
