[amibroker] AB title backgeound is transparent

[Sidney Kaiser]

I'm running WIN 7 on a laptop with AB 5.30, 32 bit program.
 
The title bar, at the top, with Amibroker, symbol, security name etc is 
transparent which makes it very difficult to read if the Windows desktop is 
somewhat dark.
 
How do I make that title bar background opaque?
 
TIA
Sid
