Okay then, I've uploaded an intermediary version (0.5.2) to codeplex . Even though it already contains many of the features for v0.6, they are switched of (still debugging them) So this is not a feature release, but it's intended for debugging mainly (to find the source of the 0x80042001 bug).
So much for the disclaimer
The version will create a log file in you local application data folder (that's something like "c:\users\<username>\AppData\Local" or open a windows explorer instance and enter "%LocalAppData%" (without quotation marks) in the address field, or hit the Windows Start button and enter "%LocalAppData%" (without quotation marks) in the search field). The file is called "edgesync.log" - you'll probably have to look for it.
So for those who encountered an error, could you please install the new version, run it to the error and then send me the content of the log file?
One word of warning though: I can principally read the content of your journal with the log information, though I'm only interested in the error source - nonetheless, a clever hacker may also use the information if you post it here. Hence, if you want to be cautious, send me your log as a private message, or if you don't trust me either, create a test journal with no confidential information.

Happy Easter, too

PS the version fixes the "empty pages crash" bug and allows to zoom out to factor 0.1 - @szegan, if you could send me a sample, then I could further improve the zooming.
