Ok, it seems to be working in IE7 now with
PopupAtom.show();
qx.ui.core.Widget.flushGlobalQueues();
qx.client.Timer.once(function() {this.longTask();
PopupAtom.hide();},this,100);
I initially tried it with a 0 timeout but the popup did not consistently
appear. It seems to be now, but I'll have to use it a while and see how
consistent it is.
Thanks for your help!

Hi Bruce,
I think you face the same issue as Daniel
<http://www.nabble.com/Global-Wait-cursor---Problem-with-UI-changes-duri
ng-events-tf3833879.html>.
The issue is that while the browser executes a block of JavaScript no
layouting is done. You have to call the computation inside a timeout.
Best Fabian
