FYI: From NI tecknical support Thank you again for your patience in all of this and thank you for posting the more complete file compilation of the 8.2 version of your code. The person who was working on this issue in R&D found another Corrective Action Request that is similar to the issue you are having. The reference number for that is 4CG9B3J1. This is set to be fixed in the next release of LabVIEW. The problem seems to be with the private data class loading the first time in LabVIEW 8.5 and becoming corrupted. Therefore the workaround is to load the private data control that might be associated with a lvclass and open the front panel and resize any control in the private data cluster. This puts a docmod on the VI so the class knows to update the saved image. I believe R&D has verified this with the Shack_Hartman.lvclass since that one was not already corrupted in 8.5. With the Variable Token class that you have loaded, it has already become corrupt so nothing can be done. This is why we needed more files in the project than you had originally provided. I wanted to provide you with more information on this problem. Again I apologize for the inconvenience this has caused you but we definitely appreciate the feedback so this can be fixed for the next release. Thanks again for contacting NI!
