I have found the same to be true when running ArcPad 8 on a Trimble Juno 3B. I am now trying to get our applets to work with ArcPad 10 and have had no luck. I have tested them in both a Windows 7 and a Juno 3B environment. I have put the applets in the applets folder and set the applet folder path to the correct location. I am unable to get them to display in the list of toolbars. The ArcPad layer files do work, however.
Also, QuickCapture does not work correctly in ArcPad on a Juno 3B. I am not able to customize the icons that appear in the toolbar. When I turn some of the icons off, they continue to display. Unchecking a box does not affect the display. This does work properly, however, in Windows 7.
I can send the applets if someone is willing to test them.
Thanks,
Matthew
