wine users - Mar 2001 - Mathematika err:dc:DCE_FreeWindowDCE

Hi folks,

after a glitch-free installation of Mathematika 4.0 using wine-20010305 
(congratulations, I am impressed with the progress over the last year!), 
the MathKernel and the console-version math.exe seem to work fine, only the 
proper Mathematica.exe notebook app fails with this error:

err:dc:DCE_FreeWindowDCE [1264] GetDC() without ReleaseDC()! 

wine does not consequently exit but stays around, asking for an ctrl-\ or 
kill. Has anybody seen this before? any experience with Mathematika. What 
can I do? The documentation, although comprehensive, does not seem to help 
me through this.

Please get in touch with me if you have any suggestions.

Regards
Max

Hmm, that error is not necessarily the real problem.

To identify what the problem with that error message is, do:
--debugmsg +relay &>logfile
Search for the last GetDC() call before the error message,
examine the ret= return address. If the return address is 0x4xxxxxxx, then
it's Wine code which is misbehaving:
Run winedbg instead of wine, use "disas 0x4xxxxxxx" to find out which
function does the GetDC call, grep the Wine code for this function and
find out why this function doesn't do a ReleaseDC before destroying the
window (?).
