Visual Studio 2015 Backspace key is not working when editing and mouse hover over is not working when debugging

Problem:

When editing Cobol source code in Visual Studio 2015, the backspace key is not working, pressing the backspace key is supposed to delete the last character but it does not do anything.

And/Or

When debugging, hover over the mouse to a variable is supposed to show up a tooltip window containing the current value of the variable but it does not do anything.

Resolution:

This is a Microsoft bug (VS2015 only).We are going to include the Microsoft recommended workaround statement in our "Known Problems" section of the docs and release notes.

Missing COBOL Language Service Support 
•         In certain install scenarios after you install for Visual Studio 2015, the COBOL language service can be uninstalled. This can result in the following issues: 
o   No colorization in the COBOL editor 
o   No COBOL intellisense 
o   No other COBOL language support in the editor 
  
Workaround: 
•         Open a command window 
•         Change directories to C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\Common7\\IDE

•         Run the following commands 
o   devenv /updateconfiguration  
o   devenv /clearcache
