App Data Disappears After Computer Sleep

Im using App on new Macbook Pro With Retina Display, running Mountain Lion OSX 10.8. Every time I put it to sleep and wake it up, all data from all cities Ive previously entered disappears. The city names even are gone. All I see is "no data" listed in the menu bar.

I have to literally delete the city name entries (which have disappeared and been replaced with the "no data" entries). Then, I have to re-enter the city names and have the App look them up all over again. Imagine having 5 or 10 or 20 cities you monitor, and having to reenter them after very computer sleep/wakeup cycle.

This is crap!
