This error message is quite odd and we have not received such reports so far. I tried to reproduce the problem in our local tests by using the sample reference file in WebDesktopSamples project -- everything worked smoothly and the precompiled content was accessed without any issues.

We are willing to advise you further but in order to do so we would need you to elaborate on your specific scenario and possibly give us a step-by-step guide that we can use to observe the problematic behavior.

The problem is the InProgressText is only showing the first time the page loads.  Here is my code.

Thank you for the snippet code.

I have reported this to WebDesktop development team to be investigated further. A work item, work item 796, has been submitted to the team. I’ll keep you updated with any news I heard from the team regarding this.
