I currently have a field rule with a lookup to an active link table that works fine on my computer running Win7x64. One of my users with the Runtime application is having trouble with all of the lookup fields displaying. So I installed Runtime on my machine and it works good for me! His machine configuration is the same as mine except he doesn't have the developer application. The pictures here tell the story. Does anybody have an explanation for this? And better yet, a resolution?
