Crashes whilst sync is happening?

I have just installed DTTG and set up syncing with part of a notebook / journal database. Most of it is a collection of plain text documents in a series of calendar folders (year -> month)

When first set up the application repeatedly crashed when the top level folder was opened.

Now it doesn’t.

I think this was because it was still downloading documents.

But then whilst I appreciate that it may not be able to show the documents that it has not yet downloaded, quitting without warning is perhaps not the best way to handle the situation.
