Hi
With version 0.8.x sometimes appears an Ajax error. I have found that when something (showmessage, uniform, etc.) is show over the component weird things can occur. So, for example, to avoid problems with show message, I do the following.
unigmap1.Enabled := False;
ShowMessage('Some message',
procedure(res: integer)
begin
unigmap1.Enabled := True;
end
);
