In pre-12.0 versions, I could use the keyboard to select my file type in the "New File" dialog. I'd tab until the list of types had focus, hit space to activate the list, then hit the first letter of my type.
In 12.0 (and 12.0.1), this doesn't work any longer. Instead, typing a letter acts as though I'd type Alt- and the letter. So, for example, typing "A" will act as though I clicked the "Add to Project" box rather than taking me to "ActionScript", which is the first filetype in my list.
Any suggestions or workaround will be greatly appreciated.
