Unable to paste the components
I encountered a very strange problem. The Xcelsius file had been created and amended for some time. Now, I copy the latest version and then do some amendment as usual. When clicking a chart, the property doesn't point to correct object. Then, I bring to front to the tabs and click on the chart again. The correct property shows. When I try to copy that chart, select copy after right click. Copy it, but found paste function is disabled. The same thing to all charts in the file. I can only copy, but not paste. What is the problem?
