When using iPad, go to Settings and go to an item like Passcode.
When you touch on the Settings button at the top to go back to the list of settings, the whole menu went blank.
Does anyone have this problem?
I just discovered toodledo a few days ago, after trying a few others. So far, it has been providing a good user experience. Hope the user interface can be a bit more "modernized" though. But, wait - it is the substance that counts.
