I noticed this with File / New / Qt C++ Project / Mobile Qt Application and File / New / Qt Quick Project / Qt Quick Application. Other wizards might be affected, too.

1. Start wizard.
2. In "Create in:" type a path which does not exist, e. g. C:\someDir. A very hard to read warning with black text on red background will appear: "The path 'C:\someDir' does not exist."
3. Click "Browse...".
4. A file browser windows shows up. In this window, create C:\someDir.
5. Do one of the following:
   1. Click "Cancel".
   2. Select C:\someDir and click "Select Folder".
6. The wizard does not update. The warning is still visible and "Next" is disabled, so one can't proceed.

This also works the other way round: Type an existing path, then remove this directory. No warning shows up and the wizard proceeds smoothly.
