He could be on holiday...
Just have some patience, some things take time, also these are not severe issues as they can be circumvented, you can save and then rename and reimport a file, annoying but a working method for now...
As I may have said before, Never used Save-As as usually I create a file in the name required, you could also just make a new file in the name you want, copy to that and then delete the original...
Hopefully the issue at hand will be fixed, also the colour highlight issue, you can modify in the options...
Replace all... that is something I use a lot in VS13, but not so much in DBPro, but you can always copy the file to another editor, perform the replace-all and then copy back... [Or open the original document instead of copying...] But again temporal fixes until the IDE is updated...
If I knew how to create an IDE myself, I would have done it by now... I know you can actually modify VS's IDE for your own coding language, but I just wish I knew how!
