I cannot even open a clean project because the project selection window is where I first encounter the bug.
I installed a clean 4.14p1 on my Mac. When I launch 4.14 from the Launcher, I get the project selection dialog box. When the mouse cursor is on the dialog box, it acts as if it is selecting something an inch below. If I try to open a project, it prompts me that the version is mismatched - since the cursor is not functioning properly, I cannot select what conversion option I wish to proceed with.
