New iMac with 10.9.1 New installation of Parallels - Trial Version New installation of Windows 8.1 in Coherence mode Whenever Parallels is activated a Windows instruction tile appears in the top LH corner of the Mac OS X Desktop, on top of everything. The instruction is in the form of a black tile and contains a large orange arrow with the heading "Switching between applications" and goes on to say "Move your mouse pointer all the way into the corner, then click to go back to the last app you were using" There appears to be no way if getting rid of this tile. Can you help?
