I stopped playing the game 2-3 years ago and have started to play again. There are many new contents or me like special operative etc. Currently I have 1 special operative and 1 defector. Now in operations tab i have a mission to use a hiring bond to hire one special operative. When i try to do that i.e try to apply the hiring bonds it shows Special Operative rooster is full,  therefore i tried to buy slots. But whenever i try to buy slots one message appears "YOU CAN UNLOCK 10 ADDITIONAL SLOTS FOR" and the game stops responding. Purchase option doesn't respond neither any other tabs except the close tab option. If i am in fullscreen mode then i have to exit the fullscreen mode or if i am in normal mode then i have to enter fullscreen mode...then only the game responds again...I have attached 2 screenshots. Please fix this bug/glitch as soon as possible.
