Script changes not visible: When I change my script code, save the changes and press the refresh button the screen is not refreshed in SAP GUI. Only after I close system can I see the changes. My scripts are on a file server.

Probably the file cache is switched on in your GuiXT profile. Scripts from

\\.... file servers are then cached and you do not see your script updates.

Either switch off the file cache or assign a drive letter e.g. Z: for

\\myfileserver and put Z:\scripts into GuiXT profile.
