ah,, I have same issue but about mouce pointer invisible,,
sometimes suddenly mouce pointer disappear perfectly when I set mouce on ds window.
but if I move out mouce from ds 4.5 window , there are mouce .
and I can select some ds menu by invisible mouce , ,
in this case, I must need to shut down ds to visible my mouce pointer,,,
I met two times,,,. after using ds 4.5.
I read the topic of invisible mouce about old daz studio , by google too
is it bug? or only my VIDEO CARD problem?
it is not easy to change video driver often,,
then,, I have one more issue about ds 4.5 property editor,
ds just crush and close window suddenly, if I move morph much in property editor ,
eg set sub conponetns, or controller. and remove,,,change node,,
if I need to report it? (other user had met this orpblem?)
