yup i can confirm that.. i too have the same problem..using windows xp build 2600 with sp2 english.. when u right click on a button and u get a popup menu saying what's this? when u click on it .. it will give a error that winhelp32.exe is corrupt..replacing that file with the original file in the windows directory fixes the problem.. so i think there is something wrong with the winhlp32.exe fle in the xpize build..
