Okay, so I have been developing a basic control system for a facility with a lock etc. I have been having a sort of bug with the login part however, when you are on the login screen, the cursor will move from the area it is supposed to be, to a point on the right margin a few lines above the text, it seems to just be a display bug as when you continue typing it will resume its current position. I think is has something to do with the 'timeDisplay()' function that is displaying the time. Now the code is a bit messy and it might be a little random, I know I have random ass things where not needed but its basically a BETA version. Anyway, any help would be appreciated, thanks!
PS. Theres two login users for debugging; login:pass and test:testing
