I can close it from the task manager to open again, but it is annoying when you cannot delete any of the features. The features can be suppressed but still the size of the file will increase with so many features which cannot be deleted.
It sounds like you might have an underpowered computer. Can you post the specs?
Its a lenovo yoga 900 with i7 - 2.5GHz, 8GB DDR3, intel HD graphics 520, 256GB SSD.
I do get the warning from the Solidworks resource monitor that the system is low on memory, but all the other features work fine.
