+1. Highlight should not be affected by selection object search and/or replace.

I also have this problem. I am working in a large text file ( 50Mb). I am performing a regular expression search, and then performing a document.selection.replace on the resulting highlighted text. Even though the search and replace is a simple operation, because the highlighting of the text is affected by the selection.replace operation, Emeditor grinds to a halt with a large text file.

If anyone has any alternative suggestions, I'd be eager to hear them.
