thanks for playing - and I'm happy you liked it :-)
about half pixels - yes - I wasn't aware of that - and someone else wrote me about it hours ago
If I get that right I guess the problem is a missing round function related to mouse render (cursor & related text) - I mean ONLY cursor and text that appears above the cursor could be not pixel perfect positioned. I'll fix that bug later on today - but I didn't notice that before - so I don't know if there's something else
Anyway thanks for pointing that out
