I created some "invisible" PNG (8bit 30x30pix) buttons in Photoshop, but I can't get them to work.

The idea is to have a picture from (a part) of an original remote control and put some "invisible" buttons on top of the buttons on the bitmap. Then I can use it as it was the real remote.

But it doesn't work. The buttons are invisible, I add actions to it and it works in the simulator but not on the Pronto 9400 itself. I try it with pagejumps as action.
I am a newbie with Photoshop, I didn't see an option to put an Alphachannel.

Other question.
What does the "scroll area on control panel" settings? Last tab on System page's properties. I hope it does something as a scrollbar on a laptop's touchpad.

Last question.
On my old Pronto 890 it was possible to resize panels with the mouse. Am I the onlly one who used this or do I overlook something and is it still possible?

You can find your answer here.

Lowpro my buttons work now! Thanks for answering my first question.

Other question: Only guessing, but I think it is an aid for migrating from another devcie with a different screen size, by recentering the screen.

Last question: resizing with mouse should be coming back in a future version of PEP.

The "System Properties\Layout\Scroll Area on Control Panel" settings allow you to adjust the default page area which will be included during page transitions (scrolling animation) when the "System Properties\Control Panel Settings\Animation Mode" option is enabled.
