I am getting lots of similar problems in developer on my client PC running same, i.e. Servoy Developer Version R2 2.0.1-build 274 Java version 1.4.2\_04-b05 (Windows XP) Database (repository and soln data) is MS SQL Server 2000, latest service packs. Server is running Win 2000 SP4 and I’m still using R2 2.0 for the server and clients without these problems. My advice, stick to 2.0.
