A logging build has been posted that may assist with isolating the problem. Please use this link:
http://www.touchpanelcontrol.com/guest/tpcontrol/Android/dev/TPControl%20v2.4.1.3778.apk
(you can download/install by browsing to the URL directly on your device)
If TPControl crashes, this build should detect this the next time TPControl is run and present a dialog including a 'Send log' option.
Also, you can at any time press both the left-bottom and right-bottom corners for approximately 5 seconds to invoke the dialog, but I would suggest doing this soon after there are any problems to ensure the issue is within the system logs.
