Now thats a different problem, I am having the same problem with my app. I have red Xs over all logical displays but my trends still show fine. I haven't been back to the job site to work on this yet, if I find anything I will let you know. My app ran flawlessly for awhile, everything worked, then the red Xs.
Things I will be looking for are: As the NI tech said, check the web browser security settings. If you are using XP, make sure internal firewall is turned off. Check user settings within Lookout (in the lookout user manager, go to the account properties for each user account and click on "groups", each user must be part of a group or you will get red Xs, even in runtime).
