And why it wasn't fixed in one of the NUMEROUS IE5/6 fixes.<BR/><BR/>I have one warning though. This fix will BREAK event handling in Opera 9. Whenever I use it, mouse events are stacked but never fired. It is only when the page is closed or reloaded that Opera fires ALL the events at once. I have no idea why a browser command targeting IE6's image cache would end up affecting Opera's event handlers... but it does.<BR/><BR/>So the best way to avoid this problem is to try to detect Opera & never apply the fix in that case.Hugohttps://www.blogger.com/profile/18359074617119057876noreply@blogger.comtag:blogger.com,1999:blog-2309581424631434054.post-42534963064897049092007-05-24T05:15:00.000+03:002007-05-24T05:15:00.000+03:00This comment has been removed by the author.Hugohttps://www.blogger.com/profile/18359074617119057876noreply@blogger.comtag:blogger.com,1999:blog-2309581424631434054.post-73633618179194522112007-05-02T16:20:00.000+03:002007-05-02T16:20:00.000+03:00Nice hack, dude. :-) Thanks for sharing it.Nice hack, dude. :-) Thanks for sharing it.Unknownhttps://www.blogger.com/profile/07723850956802550453noreply@blogger.comtag:blogger.com,1999:blog-2309581424631434054.post-78176692023453077432006-11-03T14:11:00.000+02:002006-11-03T14:11:00.000+02:00OMG, thank you!
