I was previously unable to install Opera 10.10 because it wasn't compatible with W98SE until I installed KernelEX 4.0 Final 2. Now it installed just fine........ However there is one major problem. When I click on the Delete Private Data tab the browser locks up which it did not do when I was running Opera 10.0 (the last one that worked on W98SE). I tried unchecking some of the tabs in the drop down box regarding what Opera will clear when you click on Clear Private Data, but that didn't work. Something else is causing the problem. Anyone know how to tweak that utility in Opera 10.10 in conjunction with Kernel EX? I find Opera faster than Firefox, especially Firefox 3.57 compared to Firefox 2.0. Thanks, John EDIT: I was able to resolve this problem, but I am not sure it was actually a problem that had anything to do with the combination of Kernel EX and Opera 10.10. So anyway, here is what I did: Go to Bookmarks / Manage Bookmarks / View. Check Sort by My Order Close down Bookmarks. Go to Tools / Delete Private Data / Detailed Options. Uncheck Clear bookmark visited time and Close all tabs. Delete Private Data then works perfectly.
