It stays on the tab or model space Im in at the time. The tab appears to be selected, but it is not the current window. In order to fix it I need to select a different tab, then back to the one I want. AutoCAD 2021, Windows 10 Pro. This happens on 2 different workstations I use. Any idea why or if there's something I can do to fix it? Thank you.</P> Wed, 20 Apr 2022 20:04:09 GMT https://forums.autodesk.com/t5/autocad-forum/selecting-layout-tabs-does-not-switch-to-them/m-p/11117697#M58482 murmanator 2022-04-20T20:04:09Z https://forums.autodesk.com/t5/autocad-forum/selecting-layout-tabs-does-not-switch-to-them/m-p/11117730#M58483 Is your viewport on a locked layer?<BR />Do you have layer 0 off/frozen?<BR />Are you sure you are clicking on a viewport and not an outline above it?<BR /><BR />Your exact 2021 version as listed in ABOUT command is...?<BR /><BR /> Wed, 20 Apr 2022 20:12:54 GMT https://forums.autodesk.com/t5/autocad-forum/selecting-layout-tabs-does-not-switch-to-them/m-p/11117730#M58483 pendean 2022-04-20T20:12:54Z https://forums.autodesk.com/t5/autocad-forum/selecting-layout-tabs-does-not-switch-to-them/m-p/11117743#M58484 <P>My viewports are not on a locked layer and zero is not off or frozen, however this is about selecting layout tabs, not viewports. I can pick viewports no problem.
