Hi Marco,
If you do find the focusing to be working incosistently in any Visual WebGui application, or generally in all applications, please do the same as I suggested to the originator of the thread: Please narrow down to a reportable and reproducable scenario, create a minimal reproducing application, clean it, zip it and email it to support, as per my earlier instructions.
It's very hard for us to work on such general cases when we don't have any exact scenario to work on, so it would be to your benefit an all others to report it.
Thanks,
Palli
