Problem BusyIndicator with MaskedNumericInput

[Dirk]

I have problems with the new release (2011.3 SP1) of the Telerik Silverlight controls.
If I have a MaskedNumericInput control inside a BusyIndicator control and set the IsBusy property to true and false the text inside the MaskedNumericInput control isn't shown correctly. (see pictures)

Please habe a look in the example.
Press the buttons 'start', 'set value', 'end' and see what happend.

Regards
Dirk
