Hi. I've searched for a solution to this problem but to no avail, I recently ran an apple update and installed/uninstalled syncmate and since have had the problem as seen in the attached screenshot. When I click to change anything in the system preferences the verify username & password window appears but all the text has been replaced by A's in boxes, the functions still work but it looks very odd! Has anyone come across this before and/or have a possible solution? Thanks.
