I never noticed anything like that with the onmouseup-tag. Do you have maybe an onmouseup and onclick-tag set? Because the normal mouseclick involves the onmousedown and -up-tag.

I use the following code:
<events onmousedown="mdown();" onmouseup="mup();"/>
<action name="mdown"> trace('mdown');</action>
<action name="mup"> trace('mup');</action>
When I click and release, I get "mdown, mup, mup" displayed in the log...this is for an object movie - perhaps there is some kind of bug there ?
I am using the Flash version, so no HTML5...
