Hi,

I havent't looked at the software for a while now. As I stressed out- it was more than a proof of concept, not a fully functional software. It worked for me (I've been using it on full screen) and I haven't seen the artifacts you are talking about.

I can only suspect, that it has something to do with tangens/cotangens discontinuity in 90' or 270'. This software is poorly written in terms of mathematics, as it maps pixels form the source image, to clicks on the application form - it is almost like abute force method. I had partially rewritten the software some time ago - I included zooming, and shapes drawing, but it is still not finished, so source code can not be included.

Unfortunately at the moment I do not have time to sleep properly - not to mention fixing this app, sorry :( I promis I'll have a look at it some time, but it is not gonna be anything in the nearest future...
