But, I just found something really strange - I wanted to test with a later version, but without compiling it myself, so I installed the Cygwin 'experimental' release, which is Xemacs 21.5 (beta23) "daikon". The Cygwin version can be started three ways: X (DISPLAY env var set), Windows, -nw. The X and -nw modes work better, but still have problems from dired. The Windows mode doesn't work from c-xc-f, either. Are there other packages/default settings/etc. that are set in one mode and not the others? Here's what I'm currently seeing : Using c-xc-f : Windows : Open a text file - :T (can open any number of text files at this point, all get :T) Open a non-text file - no :T (this can be a zero-length file, a text file with single line with no return, a binary file, etc.) Open a text file - no :T (can't get back to a mode where :T gets set appropriately without restarting xemacs) X,-nw : Works as expected, text files get :T, non-text files don't Windows,X,-nw : I can't ever load a file and get the :T Once a text file has been loaded incorrectly, c-xc-f doesn't work either for X/-nw. I have disabled my .xemacs so it is not a factor. Cary
