For example: touch 1.html touch 2.html chmod a+r-w 1.html chmod a+rw 2.html Open them in SeaMonkey Composer. Try using various menu items - for example, Format → Page Title and Properties. Actual results: With the read-only file, nothing happens, and nothing appears in the Error console (note that you cannot open Error console from that window using menu, either). Format: Discontinue Text Styles and Discontinue Link text is invisible, except for the hotkeys. Some items, like edit modes in View and Spellcheck as you type, seem to switch modes, but I am not sure if they actually do anything else. With the read-write file, menu items work properly. Expected results: Available features work properly, unavailable ones are disabled correctly.

Regression range is between the nightly 2007072501 and 2007072603: http://tinyurl.com/25g8v3 Probably bug 380813.

offhand, the patch in bug 380813 seems scary broken. http://bonsai.mozilla.org/cvsblame.cgi?file=/mozilla/xpcom/io/nsLocalFileWin.cpp&rev=1.176&mark=752,757#747 http://bonsai.mozilla.org/cvsblame.cgi?file=/mozilla/xpcom/glue/nsIClassInfoImpl.h&rev=3.3&mark=52,53-55,141,146,148,166,172,174#50 I'm fairly certain nsIClassInfo should *not* be one of the args to NS_IMPL_ISUPPORTSx_CI

Thanks, timeless. Neil, can you take this? /be

I think maybe we should just back out bug 380813 and try again for a later release, I think the code and feature needs a bit of work overall.

let's back it out. in reading the other bug it seems that there is a second bug that also feels that bug isn't ready. note: i shouldn't be the one to do the backout. and i shouldn't be asked to write any patches.

Enn, can you back the appropriate files out for me?

Bug 399242 was backed out to fix more egregious bustage.

This should be fixed again
