Edit Integer dialog box crash on emulator

[tcab]

Just noticed that typing any letter in the base converter "Edit Integer dialog box" crashes the Prime emulator. I am using Build: 2018 2 12. Rev:13443. To reproduce:

• Run the Prime Emulator
• SHIFT Base (if # appears, then just hit SHIFT Base again)
• Click the 'Edit' softmenu (optional)
• Press 'F' on the Mac keyboard
• Crash!
  

Entering the 'F' on the Prime emulator keyboard works ok, its only using the host computer keyboard's 'F' that causes the crash.

Is anyone else getting this? Is this just happening on the Mac or can someone on Windows 10 please try it?
