Hi,

I did post this problem a while ago with a different account:

http://community.infragistics.com/forums/p/31101/194580.aspx

I've now updated the system to 2010.1 (10.1.20101.2039) an do still get warnings in my application eventlog (see following messages).

Could you please provide a solution for this problem.

Regards
