>A barcode reader will as default add a chr(13), which means that if you are in a textbox, the cursor will move to the next taborder object. You may change the behavior of the reader, or "eat" the chr(13) by adding this to your keypress:
>

if nkeycode=13
> nodefault
>endif

no effect
only my keyboard and mouse are locked. i must only restart my system.
