[Lazarus] A manifest file X WMPaint event

[Ademir Constantino]

Dear all

I have noted something strange when I try to use a WMPaint event with 
Manifest File for Windows theme support.

For example, If create a descendent class from TEdit and I add this event:
procedure WMPaint  (var Message: TLMPaint); message LM_PAINT;

Even I do not write anything in this procedure, I can not see what is in 
the Edit when it it not focused (it is not in editing mode). That is, 
if I focus on another component, the content of the edit stays invisible 
(disapeare).

But, if I disable the option  "Use manifest file to enable themes", then 
it work fine. Is it a bug?

Thanks.

Ademir
