If you're not willing to test it in .48, then I see no reason to keep this bug open.
Note that you can run .45 and .48 next to eachother without problems. Just make sure that you rename the exe file of .48, or even better: run .48 in a seperate directory.
When you've tested this in .48, please reply so I can reopen the bug (or keep it closed if you can confirm that it has been fixed)
