After a computer crash and upon re-opening Task Coach, I'm not able to see see any of the tasks or efforts that I created in any file. At the bottom of the effort viewer it says "0 selected, 0 visible, ### total". When I open the file in a text editor I see the tasks and efforts, so it looks like they remain in the file just not visible. I have verified that I don't have any filters on in the view menu.
This even occurred with a new file. I created a new file with a few tasks and efforts, which I could see. After saving it and re-opening it it's blank again.
I've been using Task Coach for years and have not experienced this.
