I'm using mRemoteNG 1.67, fresh install.
I managed to save the connections in SQL Server (after using this workaround http://forum.mremoteng.org/viewtopic.php?f=3&t=1560) and seems working pretty ok: items get refreshed lively to another machine as well.
But in the following scenario connections tree keep refreshing every 3s (the left tree keeps redrawing and it loses the focus on the item tree on a redraw). Steps to reproduce:
1. install and save connections to SQL from machine1
2. configure same SQL connection in machine2
3. add some new connection on machine2
3. the new connections now appears on machine1 but the connections tree keeps refreshing every 3 seconds in an annoying way
