Ah, very useful.

Learned that from you. Do that standard now.

But where ? I hesitate to start things outside the message loop.

One form is to allow user to translate the application to another language
(being thoroughly fed up with the Translation Manager). It presents all text
items (captions, hints, lists, messages) of all forms. Its initialisation
must wait for completion of all other forms. But otherwise I agree.

Tried them. No success. The problem occurs only with one of the tabsheets,
whatever pageIndex I give it. No problem with other tabsheets.
I have solved it though: with the call to tabindex:=0 in loaded rather than
in the timer event handler the behaviour is as required.
