Hate to bring this up again but I tried taking a quick snap of my game again last night,first by using CTRL+F11 then CTRL+PTRSC...no luck

Pressing F1 to bring the button mapping info up indicates that CTRL+F11 is the correct way?
I was looking in the main SH3 directory,and cant see any recent JPG or BMP references to SH3.
I think I managed to take a snap ages ago using stock but cant remember which button I used.For the record,I am using the res fix for GWX3 allowing for higher resolutions.
Thanks for any help here.
