Hi Huw,

You may have already seen this. The changed tests introduce a great
number of test failures on Win9x/WinME.

I also see 2 test failures on my NT4+ boxes (except Vista) but not for 
others on test.winehq.org. I had a quick look and this is again the 
result of my display size being 997/568 (Vmware). As soon as I go full 
screen these 2 tests succeed.

Could you have a look? If you want me to test something just shout.
