Cannot edit text

[woodlander]

Thanks for your prompt reply.

I have modified the file types as below but I am still unable to edit text. Currently the settings read:

File extensions to display in text editor:
.txt;.rtf;.ini;.reg;.bat;.cmd;.csv

File extensions to display in internal browser view:
.html;.htm;.mht;.eml;.nws;.msg;.ico;.gif;.zip;.doc ;.docx;.pdf;

file extensiongs to open stored documents writeable:
.html;.htm;.mht;.eml;.nws;.msg;.ico;.gif;.doc;.xls ;.ppt;.pdf;.docx;.xlsx;.pptx;.txt

In the 'open stored documents writeable' I have tried the line without the .txt suffix included but that has no effect. I have also tried turning closing and reopening UR to after each change but no effect,

Best wishes, John M.
