i made topic about popup coming on wrong side for right handed(finger+hand is onway of all information). So it seems that this issue is in way also affected by this.

With stylus popup stays on screen. This might be becuse with figer you tap larger are and also are under popups men. with nail it again works.

.edit
or maybe not..this is definetly bug.it just worked some time with stylus but now i have to keep it on screen.
