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 (?).
