Grouped objects get unaccessible as soon as I apply an effect to the group

Hi,

is this a known bug?

As soon as I apply any effect to a group of objects, I can no longer select / manipulate / change any of the grouped sub-objects - for example they don't react to ctrl-click.

The only workaround I found is to hide/unhide the sub-object - then it gets selected.

Another odd thing is that when I click on "hide" the mouse cursor turns into an hour glass and only reverts to normal as soon as I move it to the drawing area.

Is there any option to "apply" the effects to the drawing and remove them from the effects stack?

thanks

thomas
