@mc73: Thank you for the code and your tremendous efforts by the way. I tried it and here is why I found out:
1. If I DIM this line:'EditText4.RequestFocus
It goes immediately to the disabled box in the first tab as my project does. However, if I return to tab1, then it is ok.
2. If I UNDIM: 'EditText2.RequestFocus , the code crashes as it isays that it is not initialized.
As you can see, the behavior is all over the place as I experienced with my code. Of course, I have a lot more garbage in my project and actually few more tabs. Also, I cannot place a requestfocus in the activity create the way you have it, because I have a lot of other stuff that is performed first like extraction of previous record data, listviews, calculations, etc.
