CHM reader that allows highlighting - CrossPlatform

Hi.
I'm looking for a CHM file viewer for Windows that allows me to highlight the text in the file and allows me to save the highlighting (the way Foxit allows it for PDF files). The highlighting should be saved so that it is visible when opening the document on subsequent occasions.

I dual-boot with Windows and various distros of Linux. So, it would be great if the application is cross-platform.

Thanks.
