When I save a new document, the default file name is "Untitled-1.indd" (or .psd or .ai). If I want to call the file "ProjectA.indd" when I start typing and press "P" all creative cloud apps add the file extension after the first letter then continue with what I am typing. So what should be "ProjectA" turns into "P.inddrojectA." If I only type "Pr" I get "P.inddr." If I start to delete and remove the r and the second d, it will add the file extension again so I end up with "P.ind.indd." If I delete back to the "P" and start typing again it will work and I can type "ProjectA" without InDesign adding .indd in the middle. Also, if after I get "P.inddr" if I highlight the entire filename and delete, I can type "ProjectA" without InDesign adding .indd in the middle. The same thing happens in Illustrator and Photoshop. Is there a fix for this?
