For some reason my ground floor window is half blank ( the 1/4th of the window on top is blank) and when I zoom in or out this part doesn't show anything.<BR /> It makes working a little difficult because my screen is not so wide! <BR /> I'm working on Mac OS Sierra 10.12.4, archicad 19.</T></DIV><BR /><IMG src="http://community.graphisoft.com/t5/image/serverpage/image-id/73377i0267D88FCEA280C4/image-size/large?v=v2&amp;px=999" border="0" alt="screen01.jpg" title="screen01.jpg" /> Wed, 10 May 2017 10:52:11 GMT https://community.graphisoft.com/t5/Installation-update/Ground-floor-window-half-blank/m-p/282796#M29234 Anonymous 2017-05-10T10:52:11Z https://community.graphisoft.com/t5/Installation-update/Ground-floor-window-half-blank/m-p/282797#M29235 Actually I found my answer here : <A href="https://helpcenter.graphisoft.com/technotes/operating-systems/mac-os-x-10-12-sierra/crash-freeze-display-issues-with-macos-10-12-4-update/" target="_blank"><LINK_TEXT text="https://helpcenter.graphisoft.com/techn ... -4-update/">https://helpcenter.graphisoft.com/technotes/operating-systems/mac-os-x-10-12-sierra/crash-freeze-display-issues-with-macos-10-12-4-update/</LINK_TEXT></A><BR /> <BR /> Hope it's going to be fixed soon...
