Subject Cannot focus a disabled or invisible windows with TIB_Checkbox
Author mmusetti70

First, I'm using IBO 4.8.7 with Delphi 2007 and Firebird 2.1.3.

In my form I have a TIB_Checkbox control linked to a datasource and the linked
field is BOOLEAN. And "ColumnAttributes => Field - Boolean, True Text = 'Y',
False Text = 'N'".
This control is in a tabsheet (2) of a pagecontrol.
When TIB_Query.Cancel is fired the following message appears:

"Cannot focus a disabled or invisible windows".

But this happen only when the cursor is over a register where the field BOOLEAN is True (Y).

What is wrong ?
