Build tool error

[PresidentSmith609]

There is a weird glitch happening when i accidently press the (previous) yellow arrow button sometimes, the build menu disappers, like nothing appears.The build menu turns white and nothing can be seen. It also happen with plugin menu also.
Also if i click the build, demolish, preview button sometimes, the button gets stuck in the pressed mode/form due to which i can't use that menu. The icon turns from forum blue to deep blue indicating its being pressed even if nothing is there.
Soon i will provide the images for reference. Hope you all can fix it with ideas.
