Arnova "7 G2" - odd touch issues

[Guest glossywhite]

Bought an Arnova 7 G2 from eBay. The guy said touchscreen didn't work, but now I've flashed "kasty-ez_arn7g2-40-043-1_5G.zip" update.img to it, and it boots up… but the touchscreen is erratic, and as usually is the case, the [ [OK] ] button won't allow me to press it after then initial screen calibration. But then, sometimes, the screen will allow me to swipe around BUT not click icons… but I CAN click the app drawer icon. Is there any reset I can do (I've already done a full wipe from ICS menu using a USB mouse for navigation). Do I need to REMOVE OTG USB mouse when calibrating? Etc etc…

SO bizarre! Any ideas you lovely people?

Thank you
