Hi, I am using Athena in Windows and I have been having trouble with some project files. I would like to determine the cause: after closing the original file I am unable to reopen the project file again properly. I have attached a file to demonstrate the problem (test1.prj) Saving different versions does not help. When I open the file, no spectrum is displayed. (If I click on a file during the importing then that spectrum will remain displayed). At the bottom the "removing background..." never says "done". It seems like everything is working except the graphing window. I haven't been able to determine what is different about this data from other data that opens without any problem. I would appreciate any help with this. Thanks, Lisa Lisa Van Loon, Ph.D. Industrial Research Scientist lisa.vanloon@lightsource.ca
