Bad visibility of modified or focused symbol in Watch Window

When a value is modified or a specific symbol is focused, text is colored red and background is grey which provides bad contrast.  In updated version of winIDEA this has been changed, but the older default color stays in saved option values. 

Possible solution

Delete *.XTRF file to see the change.

1. Click Start or Cortana search icon in Windows 10.
2. In search box type in %appdata% and select the folder. 
3. You should be located in AppData / Roaming file. Delete [USER]\AppData\Roaming\ASYST\winIDEA\winIDEA.xtrf.
