WARNING: GUYS DO NOT UPDATE YOUR POLARIS APPS, IT WILL RUIN YOUR FILES AND DOCUMENTS. It's "undo" deleted anywhere in your progressed works. Can't explain it...but in one word "MALFUNCTIONING". Got a problem, when I editing text, after I select the word from my keyboard suggestion the next word is distorted, some letter(s) is/are missing. Hopefully the developers may hit this problem in their troubleshooting, thanks for this free apps!
