Hmmm, possibly.

Are you able to install Fiddler (http://www.fiddler2.com/fiddler2/) or similar to see what the response from the server is when you launch the folder picker?

Many thanks

Ok, then that's a little bit weirder than a timeout.

Can't think what could be null, but I can try and put some more checking within the CreateMediaTree function and see if that helps.

I'll try a create a DLL for you to test, as it looks unlikely to be something I'll be able to replicate.

Hi Paul,

I've just uploaded another release if you've like to reinstall (or just swap the dlls) and give it a go to see if it resolves your issue.

Many thanks
