------- Additional Comments From mikolaj.zalewski@gmail.com 2006-25-09 10:37 ------- This problem was caused by our comctl32 returning -1 to a TB_ADDBITMAP with wParam==0. This caused WM_CREATE to fail and the program giving two not very accurate error messages: "couldn't create empty document" and "Unable to find 2005 Tax Return File.ta5".
A patch to fix it have been accepted to GIT - if you could download it (or wait for wine 0.9.22 when it comes out) to check that it works for you too.
