50g strange artifacts, dashes


I was working with equations in the 50g and cleared a mess off the screen it left dashes at the top left of each soft label. The single quote marks failed to work. Hot or cold reset took all out but one in the middle. I removed an AAA cell and waited, no help. It passed all tests. I removed the memory cell and an AAA cell and waited. no help. I removed the memory cell and a AAA and left it for hours, recovered. Sam
