SlickEdit 2009 introduced the capability to have different comment colors for line comments, block comments, and doc comments. SlickEdit 2008 only offered a single color.
If you prefer a single color, select Tools > Options > Appearance > Colors, locate the comments group and set the colors for the corresponding comment types to the same values.
The two sets of block comments being colored differently is odd. I suspect one is being interpretted as a doc comment. It doesn't begin with /** does it?
To configure which comments are recognized as which types, select Tools > Options > Languages > your language > Color coding. Then select the Comments tab. You'll see a table with comment begin and end patterns. The items marked as "LineComment" are colored with the "Line Comment" color. The items marked as "MultiLine" are colored with the "Block Comment" color, if there is no check in the "Used for API documentation" checkbox, or colored with the "Documentation Comment" color if there is a check in the "Used for API documentation" checkbox.
In C/C++, the defaults are:
- // - Line Comment
- /* - Block Comment
- /** - Documentation Comment
- /*! - Documetation Comment
