--- Comment #10 from Piotr Caban piotr.caban@gmail.com --- Reverting this patch will break some other applications so it's not a good idea. You can probably workaround the issue by installing native ie6 or ie7.
This is not an easily fixable bug. I'm planning to look on it during code freeze but last time I was working on it I didn't know how to fix it. It also looks that WBaduk is not working very well in recent wine even if "ieframe: Added OleObject_Close implementation" patch is reverted.
