If you ever run into this problem, try updating your java to the latest version "8", then in Minecraft Launcher, goto "launch option" tab and click "add new", name your save what ever you want to name it to. I named it "Forge 1.7.10 x86", and select version "release 1.7.10-Forge" with the latest version of forge another words select version: "release 1.7.10-forge10.3.14.1614-1.7.10". Then turn on java executable and select the folder and file "C:\Program Files (x86)\Java\jre1.8.0_121\bin\javaw.exe", then click save, goto "news" tab and select your added saves and then play the game and the problem should be solved. It worked for me. I named my save "Forge 1.7.10 x86". This should stop the game from crashing when you right click on the screen in Minecraft.
