That is great news. It has been a big gap since the last version was released, so it is good to see development continues. I will have to try this out later. ;)

Tried Winuae and to me it seems it's geeting slower every release since 1.5.3, on single core computers. And on XP Sp3 any system i've tried it takes a bit to pop up the menu with f12 and releasing the mouse with midle button.

Dos box still haven't got the time to relly mess with the new option, but it really seems very good.

Just realized, the slowdown on F12 and middle mouse button release are issues with Kaspersky Internet Security 2009 and not a Winuae problem. Deactivating the AV makes winuae respond to this calls normaly.:hmmm:

I also use Kaspersky. Will be interesting to see if the same happens for me.

Maybe it is the proactive defence part of the program causing the issue. I had a similar issue with Kaspersky and some Adobe software, including Premiere, Soundbooth and Photoshop. It would cause the applications to either not fully load, or would cause errors when it did due to blocking specific file access they needed.

You'r damm right! :thumbs:, it's the proactive defense! Deactivated it and now everything works smoth. thanks!
