Thanks, that has sorted it... I think the link from "try it" on the web page may be downloading the incorrect version?... the downloads page itself downloads 1.0.1217.1 which seems OK :)

Hello,
there has been a bug that causes this, in builds up to 1.00.502.1. The bug has been fixed in build 1.00.1103.1 (on February 29, 2012) and later builds (including the build currently posted on our Web site).
Aren't you using one of the older builds? The best way to check the build number is to right-click on OpcLabs.EasyOpcUA.dll assembly, select Properties, then click on the Details tab. The version is listed as "Product version" or "File version".
If you are using the right build let me know and I will investigate further; however, I was unable to reproduce the problem using our latest version.

Wanting to query the nodes that exist on a specific branch to populate a tree view etc.
Using the opc foundation test ua server
BrowseDataNodes("opc.tcp://localhost:51210/UA/SampleServer") seems OK
BrowseDataNodes("opc.tcp://localhost:51210/UA/SampleServer","nsu=http://opcfoundation.org/UA/Boiler/;i=1240") crashes with Cannot evaluate expression because the current thread is in a stack overflow state.}

but BrowseDataNodes("opc.tcp://localhost:51210/UA/SampleServer","ns=4;i=1240") works fine
Any ideas as to what the problem is here?
Thanks.
