Latest version (1.1.3) contained one serious bug. New connections wasn't appear in Database Navigator and connection editor dialog didn's save properties correctly.
This bug was fixed at evening of Apr 25 (it is fixed in the distribution which currently available for download) but those who downladed latest version before this fix may experience difficulties with connections management.
We recommend these people to downlad latest build of 1.1.3.
We are very sorry for this very nasty bug.
