urghhhhhh,
yes maybe a win tech could spot the issue.
It's a new laptop, so wasn't expecting any issues like this, but luckily it being new, also means that if I need to reset then I've not got too much stuff on here atm. would rather not, but if necessary could try that.
I can use other viewers, but it all affects my workflow, as I habitually open and view files from explorer.....
Cheers mate.
