Some users (particularly novice ones) may not realize that their web browser doesn't support the WYSIWIG editor and instead think that TWiki is "broken".

The attached patch uses JavaScript to test to see if the user's browser is known to support the WYSYWYG editor -- currently, this includes Firefox 1.5 and later and Microsoft Internet Explorer 5.5 and later (this list can be expanded once WYSYWYG support in Opera, Safari, and other web browsers starts to work properly).

This was originally reported in TWiki:Codev.DisableWYSIWYGforUnsupportedBrowsers, but moved here at the suggestion of TWiki:Main.CrawfordCurrie. The patch has been updated to include more explanatory comments.

---

• We don't have separate wyiwyg and raw edit buttons
• TinyMCE does a decent job of disabling itself where it doesn't want to work (these days: browsers on mobile devices)
• We have the TINYMCEPLUGIN_BADBROWSERS var to disable the editor based on UA string

And so seeing as this bug is from early T4.0 times, closing.
