problems selecting curves or lines in V2

 From:  bigK

i have just installed Moi3d v2 on windows 7 64 and have problems selecting curves and lines.
it seems that the cursor is off concerning these selections, when i framepick it works as expected though. (meaning as soon as the frame covers the whole line it is selected)
moving over a curve with the mouse pointer does not highlight it and clicking on it does not select it. sometimes when i click somewhere else it is selected.

in v1 or the latest beta i have not had this behavior, but these were not installed on this pc with windows7 running. they were installed on a winXP system.
is this a known problem ?
