Yes, we use WKIX32.EXE for both Logon and some Citrix launch. Others use the Citrix InFuse client and it only publishes the application without any special script involvment.

We did run into an issue though where using the /i switch of WKIX32.EXE would hang one of our programs. We quit using the /i switch and I don't remember enough of the details to explain here, not sure which application it was.
