The code it's simple

in the mousemove event say something like this

thisform.object.top=nycoord


it's true that I have only tried on WIN2k with no SP and also winXp with no SP but I think that WINXP it's a win2k with all SP3+ something.
I'm telling you that there is some wird stuff about this WINDOWS media player. I'm developing a Report designer now and the only way to make it work under winXP it's to start a Windows mediaplayer.
I have only ATI Xpert 2000 in my office. Could that be the problem?
