Just had to load Windows XP on my desktop as '98 Explorer died a sudden and unexpected death !! Having some fun with a few different softwares as they do not want to play with XP but wondering if anyone out there is using Step 7 on a XP platform and has had any problems ?? I am informed that Siemens will not have an upgrade for XP until November.. GX Developer & E-Designer seem to be OK......so far !
