Open shulist opened 5 years ago

shulist commented 5 years ago

Expected Behaviour: A second instance of TDT should open when the icon is selected. Actual Behaviour: The app freezes and then crashes with the error message

An unexpected error ocurred Object reference not set to an instance of an object. Please see Help -> Show Error Log for more details

This appears to have been previously fixed as I use multiple instances regularly and have never run into this issue.
