Sorry I can't be more specific on the amount of time, I would say at least a week, but I noticed that I'll see this error and it only goes away if I relaunch the program (not stop/start the web server)
Error: ENOENT: no such file or directory, open '/var/folders/kgqy0dz4892ggdfjzgfn3vhbw00000gpT/.com.creativeland.companiondashboard.cuHe4H'
