I have a question relating to the on-screen keyboard on my Surface Pro 4. When detatching the tablet screen from the keyboard on my Surface Pro 4, the on-screen keyboard appears as expected in text-entry instances (notepad, Word, Internet Explorer). However, I have created an ActiveX Text Box in Excel, and, upon clicking on it, the on-screen keyboard does not appear - almost as if Surface does not recognise an ActiveX Text Box as a text entry window per se. (NOTE - when the screen is attached to the physical keyboard, I can type in text to the ActiveX Text Box just fine). Does anyone have any suggestions?
