Hi
when there is active timer on page and window with this pages is hidden (in our case whole client is hidden with system tray), the timer heart beat listener calls
Page.callServerWhenPossible - which checks for
getOwningDialog().isShowing() is false
and postpones the call to event queue, on next queue loop nothing is changesd so the call is again added to queue and so on

This leads to unnecessary high CPU load.

UPDATE: We actually need this timer to run while window is hidden. So there is no need to delay roundtrips until window is shown.

It looks like the issue was not resolved completely.
There are still complains about high CPU load in that hidden window with timer, when this window is initially hidden. When the window is shown then hidden back - CPU load drops to normal (after it is shown).

...ooops. you start the UI with initial state "closed"? ... So, yes, the correction of last week only is active after the first opening of the window. We currently do no see if the window is not active due to it's just in the build up process or due to being hidden...

will check, asap...
