Hi, you didn't set the Background property of the "Border" in your ControlTemplate thus leaving it "null". Hence there is nothing to 'sense' the mouseover. In fact, even if you move the mouse fats over the Button-content you get a reaction. So, either set it via TemplateBinding or at least set it to Transparent - anything but "null" will do. Cheers Jürgen

Write the Triggers in ControlTemplate. That would work. Castle Rider What if I freeze??? Don't forget to breath... My: Website | Yahoo Group | Blog Spot /xml>

Thanks. That is one way to solve the problem. But what I am really looking for is a way that COM infrastructure would take care of. What this means is I should not report error to the user, instead return the reference of the already created COM object. If the COM server is launched as service and all users connect to it using CoCreateInstance, they get the same reference. But when the COM server is launched using the current user account, things are screwed up as a second instance is created. Instead COM should not create the second instance, instead return the reference of the COM object hosted in the service. Thanks http://vivekragunathan.spaces.live.com Programming is an art.
