Notes:

Note 1: ActiveX controls like WSpell work only with browsers running on 32-bit Windows systems. Internet Explorer can use ActiveX controls directly. Netscape can use ActiveX controls, but a plug-in is required in the client browser and the process involved with using an ActiveX control is complicated. WSpell has been tested with Internet Explorer, and comes with instructions for use with Internet Explorer. WSpell has not be tested with Netscape.

Note 2: If you intend to use WSpell in an Internet (as opposed to intranet) Web page, you may need to digitally sign a CAB file containing WSpell and its dictionaries. A CAB file signed by Wintertree Software, containing WSpell and the American English dictionary, is available. If you want to include different dictionaries, or want to sign the CAB file with your own signature, you must obtain a signature from a company like Verisign.
