download the new 1.0.1.3 version, which fixes various bugs, sync being one of them.

I was using 1.0.1.1 and noticed several unusually very low coin awards in the past few days. 1.0.1.2 seems to have fixed the issue, and I just noticed 1.0.1.3 was out so I downloaded it as well.

oh and 1.0.1.3 finally fixes the giant Linda logo in the 'About' screen screwing up the window

nice to have active devs again fixing issues...thanks nisanb
