FM unisono problem? and strange GUI control problem

[Oberheim 8000]

FM & PM problem with unisono:
I dont know if it is a bug or no, but if use Phase modulation or FM and use more voices, it sounds only more louder and dont sounds like more voices. I tried use detune, but no change, it sounds like the detune not working or voices are dont want make differences. If i use voices for global section, that work properly.


Graphical User Interface control problems:
The GUI of SynthMaster is strange for all controls except knobs and buttons, but maybe for knobs too.

For example:
In MSEG is hard select node and move it, It looks like the gui is shifted.

In ARP gui in pianoroll mode, if you move the note, it is become not under mouse cursor but shifted above.

Moving nodes under MSEG, 1D nad 2D lfos, ADSR and others:
If you move with nodes, the node gets own life. If my cursor have more distance from original position of node (while drag node), the node get half distance from previous position. Thats looks like it is for precise values, but if look for number values of node, the values gone strange. For example in MSEG where from 9+ values sometimes i get immediately limit value, or from short time.

EDIT: and i dont know it is me or it is a SM problem. I have notebook, with 2 graphic cards (from i5 and AMD ATI) if i change to ATI problems are still here.
