So have you ever wondered when making changes to the settings of programs why they have an OK button and an APPLY button? Is there a difference between the two and if so what is the difference?
Well, I've always wondered myself why they didn't have just one or the other - not both, until I discovered why.
Basically, both buttons perform the same function in regards to making the same changes you require. However, the main difference is that when you click the OK button the settings are applied and the window is closed. However, when you click the Apply button the settings are applied and the window remains open. This way, you have the option to make changes until you are happy with what you want without actually closing the settings window each time a change is made. Capisci? Good!
