I noticed that when running my application on a T3, opening an help dialog (either by calling FrmHelp or by clicking (i) in the top right corner of a dialog) opens the DIA if it was previously collapsed. The DIA is then again collapsed as I close the help form and return to the underlying dialog.
This problem does not arise with built-in applications. Is it because those applications do not use the FrmHelp API and redefine their own help dialogs, or is there any trick to have FrmHelp not opening the DIA ?
The built-in apps on the T3 are using a custom DIA API that PalmOne developed separately from the PalmSource DIA specification. That's why you have to install the DIA support PRC files on the device -- they hook into the OS and remap the standard DIA calls to the implementation that PalmOne shipped. As far as I know, the PalmOne implementation is not public, and they encourage use of the standard API instead.
