Hi, thanks for the reply, just to explain a bit more.
I understand that it is possible to code a HTML page to launch an external JS script when a button is clicked so this is what i am aiming to launch it with. If I could find a way that I could launch an external VBScript I'd be happier as I dont seem to be able to code it (in VBS) the same within the HTML file - but like I said I am new at this
I would like the script to select another application (reflections - terminal emulator client) which is connected to our production system. Once it has selected the other application i want it to send a key (F10 - which will launch a macro within the reflections session to copy information from it to the clipboard). and then return to the IE window to paste the info from the clipboard into a text field on the HTML page.
Cheers
