Well, I've found another solution. The reason the buttons don't display any
larger then 16x16 is because...

SendMessage(hTool,TB_AUTOSIZE,0,0);

....must be placed in the code. Next question (I should probably start a new
thread for this) how do I enable tool tips? This is very easy with MFC but
without it I've found very little documentation. Can anyone point to a good
example?
