In answer to everything so far, I have put version 18.104.22.168 of MJRW at http://www.jacobsm.com/index.htm#sft Here are the changes :- Changes 22.214.171.124 to 126.96.36.199 1) Fixed bug with changing the timer's repeat rate. The loop engine now responds to changes immediately. 2) Fixed bug with blank lines causing errors, and subsequent malfunction of the program. 3) Made top window read-only when MJRW is started, and added an option to toggle the read-only setting. 4) Added function key F6 functionality to minimise MJRW back to the tray. 5) Added value hkey_local_machine\system\currentcontrolset\control\session manager\environment\path to all lists.
