I've started working on my first DX theme and have run into a problem...

I've made my taskbar and systrays, and the taskbar object works just as it should, but the systray seems to be nonfunctional. The icons show, but when you click on them nothing happens.

I know that somewhere I'm missing something because if I click on the systray in a theme made by someone else, they seem to function just fine. Any ideas what the prob is?

TIA for any help you can provide.
