Thanks this put me on the right track. What solved the problem :
       1) the wxStaticbox sbox prevented everything else to be displayed. 
            On linux and VMS with wxGTK/wxGTK1 this is not a problem.
       2) In a "MOUSE-EVENT for canvas" I used wxPaintDC dc(this). When I
            changed this to wxClient( canvas ) it started to work.
	    for wxGTK/wxGTK1 on linux and VMS there is no difference

What is the reason for the differences in behaviour for wxMSW and wxGTK? I
chose wxWidgets for its portability, so that I could develop on my favorite
platform and when all works just put it on a windoze box without effort.
