Hi,
I'll jump in without knowing exactly what David meant, so I'll speak for myself.

*why* do you need to start more that one IDLDE session?

So here is my way of doing things. The idlde (development environment or simply DE) is made to develop code. And to develop code, one DE with one workspace is more than enough (at least for me!). If you have more persons developing code together then they will be using different PCs and you will need to manage revison/version control.

To *run* code you have *also* other options:
1) the development environment of course
2) the idl_idlbridge to run more that one process at the same time (see http://www.exelisvis.com/docs/IDL_IDLBridge.html)
3) the idl virtual machine or VM can run .sav files ( http://www.exelisvis.com/docs/StartingVirtualMachineApplicat ion.html)
4) the command prompt in windows is also another option and does not require a workspace and you can run multiple instances.

That said, here is how I use the above. I normally write code in the DE, test it or execute it within the DE and execute the final product (.sav) in the VM. In the VM I can run as many processes as I want. The idl_idlbridge is a little bit more tricky and there are loads of posts describing what it is useful and not useful for.

Hope it helps.

Cheers,
Helder
