Computer temporarily freeze when pressed F11?

Question

Im not sure when did this start, but when I press F11 on my keyboard at any given time my computer tend to freeze for 1-2 seconds with HDD lights fully lit. The effect goes away immediately and if I press F11 again the effect will be further reduced. Upon pressing F11 the third time, there is no noticeable freeze. 

This is kind of a problem for me, as for one of my programs I require to repeated use F11 for one of its functions. When I do this, the computer will freeze for longer than if the computer was not under load - up to 10 seconds. After the freeze, the effects are similar as described above. Whats more, the function that F11 is supposed to achieve in the program was not executed. Even if i kept pressing F11 in the program, nothing happens. This is quite annoying and could anyone please help me with this? Thanks.

The helpful information is what software requires you to press F11? and what function is F11 supposed to do in this program.
F11 on most Windows based PCs is full screen mode, if you are using a graphics based program it is possible the "freeze" is due to a resizing of the work and possibly an auto save of the original before the program works out it is already in full page mode. The reason it does not do it on third press is because there is no further data to save.
tell us the program and the function you expected F11 to perform and "we" may be able to help further.

Buttons can have more than one function

f11 is used to auto save.

Your computer is not freezing up,  it is just busy saving what is on the screen.

Try looking for a button on your keyboard named 'F Lock' or 'Function lock'.

Press that and you should be good to go.
