type 13 mismatch

this should be very simple. I install iMIS on the internal server, desktop, casual i15 and public i15. everything is working great. when i log in to the server and log in to iMIS desktop it works great. public view and casual work great. when someone else logs in to the server they get the type 13 mismatch error on the desktop although the other 2 work fine. the desktop on this server works only for my log in. if they install the desktop on other pcs it works fine. we are using terminal services to link to the server for this.
