Adobe what did you do!!!
Acrobat Pro DC
Update release version 2015.009.200.69
Opened Acrobat this morning and was greeted by a lovely intro showing new features installed in the latest release. Once such update was 'tabs', now grouped together in the top bar. Great, I thought a nice way to have multiple documents open, yet easily accessible. BUT WAIT!! Part of my workflow is opening multiple documents to combine, edit and swap pages between different PDF files. I do this by displaying two or more files together on the screen at the same time using the menu command: 'Window > Tile > Vertically'. I would then have multiple PDF files in view and by selecting 'Organise pages' I can 'drag-n-drop' pages between each file. With this latest release the 'tabs' don't allow this menu command to work at all!! Adobe you just destroyed my smooth workflow in one go.
Not sure how I can get this back to how it was other than: drag out each file to a new document one at a time until they are separated, then use the menu command 'Tile' and it should now work.
Help. Anyone got any other ideas please?
Adobe you really need to be more careful. Now looking for third party method. Yids.
