Hi. Thanks for your input. I did download this application, and, yeah, it 
appears that my patch regresses it. However, I did a bit of debugging of my own 
and I don't think that the real problem in RAdmin case is not sending the 
message to the parent, just like it isn't in DCPlusPlus, the real problem seems 
to be on toolbar's side again. Sending message to parent in tooltip code 
probably simply works around toolbar's broken behavior. In this case I think 
I've identified a line in toolbar.c that fails to properly detect empty string 
causing not appearing tooltips in Radmin. I'll try to submit another patch with 
this fix shortly.
