I installed Unity Tweak Tool and after this is when things went to hell. I un-installed it, though, also removing the Unity Greeter. I realized Unity Tweak Tool would not work on Elementary. This is where things get confusing. Let's say I finish recording my desktop with Kazam and click "Save", the file browser window opens for me to name my file and choose a folder, yet there's nowhere to type. Same goes for saving an image from a browser like Firefox. A file browser window opens and I cannot save anything. I can't type, hitting enter does nothing, etc. Does anyone else know the solution to this or can anyone give me feedback? Thanks in advance.
