 This is the default.

 And this option is invalid with wx configure itself. Not that it changes
anything, of course, as configure just ignores unknown with/enable options.

 Can you reproduce the problem in a sample? I.e. if you just add 3 lines of
code needed to load wxGrid from XRC to minimal sample, does it happen
there? If yes, please show us the backtrace of the sample. If not, you
should try to understand what's the difference between the sample and your
program. At the very least, give us the backtrace of your application. But
it's very difficult to help you without any more information.
