Description Robert Jeppesen 2014-07-12 03:04:25 UTC 
Minor bug: 
Given this code:

```fsharp
let abcdef = 123

let b = abcdef + 123
```

Click on the first `abcdef`. Both highlight. Now click either on another char in the highlighted var, or click on the other `abcdef`: Highlighting is removed, but doesn't reappear.

This was first reported in the F# binding but this is not F# specific. https://github.com/fsharp/fsharpbinding/issues/643

I have checked this issue and I am able to reproduce this issue.

Steps I followed:

1. Create an "F# Console application" on XS
2.  Write the following code

     let abcdef = 123
     let b = abcdef + 123

When I click on the first "abcdef" I observed that both the variable highlighted and when I click on the second "abcdef" the highlighting is removed. Now, when I click on any other line in text editor and again click on second "abcdef" this time both the text is highlighted but when I click on first "abcdef" the highlighting is removed.

I also observed that the highlighting is working as alternately It depends on what text ("abcdef") we have selected first.
