Hi Dave/Team,
We found that - Query window does not give any error, if it does not able to open the selected file.
The problem was: it is not able to convert the contents of the file in Unicode characters. :-(.
The patch for the trunk throws a warning from wxUtfFile::Read function and returns with -1.
The patch for the REL-1_10_0_PATCHES branch throws a warning only from frmQuery::OpenLastFile function.
