Hi Marko,
Thank you for the time you took to test it further.
If i get a chance, I'll do a clean install of Windows and see if I can isolate whether or not another application is interfering with the function. So strange for me having such vastly different machines displaying the same characteristics, so maybe something else I have installed common on both machines. I'll let you know if I come across something...
Cheers dude,
Cass.
