I have been havingthe same problem and what I had to do for the moment until spb fixes it was to disable the close button feature and use the dell switch. Its no too fancy but gets the job done.
Hopefully there is a fix son because I tried Wisbar 2 and I think it is much more unstable than pocket plus (obviously when Pocket plus was working). I like the skins od Wisbar 2 but the program just didnt work that well for me. I got tired of having to tap the start icon several times just to get the right menu to drop down.
I never ntoiced how much I use some of these programs until I have to stop using them. I have a nice little pit where the close button is and now that I am using the dell task switcher I am making a new pit
