I've been using Freemind 9.0 for a little while, and have found that on occassion, I have created a table in the 'Notes' section of a Node, and saved the file. When I reopen the file the whole page has become corrupt and the information in the notes page is now filled with html text. This text is non convertible, and even in the HTML Code view tab I cannot revert it back to the actual table I had created.
Please help! How do I fix this????
