I am using Npp4.7.5.
When I type a doxygen special command, it is not highlighted properly.

To reproduce this bug

1. Open a new document
2. Switch language to c++
3. Type /*! in the first line
4. Type \param or \todo on the second line which is a Doxygen special command. The word will not be highlighted

Highlighting is fixed when
1. adding a space at the end of the first line
2. switching for another window or another tab in Npp and going back to the current tab.

If you add a new line, the special command on the previous one is not highlighted anymore.
