if you think the variables popup might be showing up outside of the desktop space(like when you switch from dual monitor to single, and stuff is outside of scope)
a lot of times if you change your screen resolution from current to something smaller(ie 1600x1200 to 1200x768) , the OS will move alll windows into the new desktop area so you can get it to float int he touchable area again.
then you can change it back to normal again.
see if that works for you.
