STE Mouse Problem

[avctech]

Hi All

I got a 520STE from eBay for £30, needed a lot of work.

Anyway, to cut a long story short, all cleaned, upgraded to 4Mb and working a treat, except when I left click the mouse, nothing happens unless I hold the button for 5 seconds or so, then it clicks.

Mouse is from my Falcon and works fine so I am guessing it is something to do with the keyboard.

Anyone any ideas? Could it be the SN74LS2?
