I really like the app, but with this version the bug is so heavy I even can't use it anymore. In version 3 at the start a litte dialog showed up (some jpg missing), but I don't cared, after pressing OK it didn'i bother me anymore.

With this version the dialog shows up every 3-5 seconds:

I don't know what kind of squid.jpg is missing and where, but this makes the app unusable.
