shifting mouse cursor on a link

[morican]

I have a series of movieclips that are acting as buttons on a site. For some reason, when mousing over on them, the cursor jumps for a split second to the upper left of where it should be and then finds its place. This occurs on all movieclips in the project that have actions associated with them. A typical piece of code on any given clips is as follows:

on (rollOver) {fade_learn01 = true;}
on (rollOut, dragOut) {fade_learn01 = false;}
on (release) { this.mc_projects.unloadMovie;
_root.projecttype = 1;
_parent.gotoAndPlay("01A-1")}

The beta is located here so you can test it yourself:

Click on the 'G' to expand the menu and then try selecting any of the items.

Has anyone had this problem before? Could it be a platform issue? I am using IE on Windows2k.
