Inadvertent firing of smoke - Windows Surface Pro 2 with keyboard - SOLVED

[David G]

Hi. I may have to figure this out myself, but I've got a problem with smoke being automatically selected when I fire. It's intermittent. It is more of a problem in indirect fire, as I might not realise my error until I see all that lovely smoke descending repeatedly on the same hex when I get the turn back from my opponent, a frustrating way to burn through all my smoke and fail to do any damage to the enemy

It is clearly a product of my using my Surface Pro 2 tablet with the touch keyboard. I will no doubt have to figure out the cause myself, but just in case anyone else has had it?

(And if anyone should raise an eyebrow at attempting to play on such a device, it is good for everything else including Office, and now what I travel with on the train each day given my old XP netbook's OS is no longer supported by Microsoft ...)

EDIT -it's the Type keyboard I have not the Touch.
