Trouble clicking the scroll menu in everything in the client.

Ok so as the title says, I have trouble clicking the scroll menus in practically everything in the client. For example: I want to change the bot from practice to do arena's. Now I have to click the the damn thing a thousand times for it to bring the menu so I can choose Arena. Oh and by luck if it DOES come down, it can disappear in two seconds after I move my mouse. This is pretty exhausting as it can take 2-5 minutes JUST to change the mode, and it does happen to what hero the bot should choose. This is a super annoying bug and can anyone please tell me what's the problem? Thank you. Note: This effects EVERY scroll menu in the client, not just changing the mode. It makes using the client very irritable, and help would be very much appreciated.

 

What version of windows ? mine is windows 7 and its smooth ? could also be other software interfering, try disabling all other software like antivirus, just the game and the bot??

 

Yes I am using Windows 7 and it is smooth. I always disable antivirus when running programs like these, and yes I also turn off any unnecessary processess.

 

and how do I remove the microsoft things exactly? I know it's a total nooby question so don't shoot me

 

I was not able to find microsoft .net framework 4 client profile and microsoft .net framework 4 extended, so I removed the microsoft 4.5.2 framework, and the other two things mentioned. I downloaded the wizard, ran it as adminstrator as well as the other installations, restarted pc, ran windows update, restarted pc, and the problem still there.
