I get repeated "Grindstone failed to save your data" warnings


Hello All,
I am getting these warnings every 5 to 9 minutes. The OS is Windows 7 and Grindstone is idle (no Work item selected, no timing). The log is always the same:

– IOException: Cannot create a file when that file already exists.

at void System.IO.__Error.WinIOError(int errorCode, string maybeFullPath)
at void System.IO.__Error.WinIOError()
at void System.IO.File.InternalMove(string sourceFileName, string destFileName, bool checkHost)
at async Task Quantum.Client.Windows.App.SaveDatabase(bool backgroundSave) in C:/Source/Quantum/Quantum.Client.Windows/App.xaml.cs:line 2033
at void Quantum.Client.Windows.App+<>c+<b__220_0>d.MoveNext() in C:/Source/Quantum/Quantum.Client.Windows/App.xaml.cs:line 1868

Any suggestion?

Update: I restarted the PC and the warning hasn’t appear so far. The log shows two exceptions after the series of IO Exceptions above:

Any connection?

Thank you!
