After some playing managed to get it all working now - operator error im afraid I did not think to check the target device in the programmer drop down box..... wrong device - lol.

Thanks to Darrels comments about the progpic2.exe this pointed the finger of suspicion.

It makes a difference even though i was compiling using the -p16f627 switch on the compiler command line, progpic2 had other ideas.

Hopefully I can now get on to what I need to do which is measure low frequencies below 250Hz accurately - any ideas here would be most welcome

Once again - many thanks
