This is a warning for all developers working on Today plugins and/or additional SIPs for WM2003SE...
If you use a HighDPI PDA with WM2003SE (VGA screen, like the Toshiba E800, and the soon to be released Asus A730), then any application is either "pixel-doubled" or uses specific high quality large bitmaps and icons, in order to make the PDA easier to use. All of this consumes large amounts of memory (4 times as much generally). For most applications, this is not a problem.
The problem is that for Today plugins (like or ) and for additional input methods ie SIPs (like Calligrapher, Resco Keyboard or MessageEase), the GDI resources are all taken from the main system process. And starvation can happen quickly, resulting in plugins disappearing or input methods not loading (plus a large variety of side effects up to PDA hanging and soft-reset).
This can be quickly reproduced by anyone with a HiDPI (VGA) PDA : just load some graphical-intensive Today plugins, add an extra SIP or two, and you will be able to see the problem of the additional SIPs not loading, or even the Today plugins disappearing after a soft-reset.
If you are working on such an application, it would be good to either think of a workaround if it's possible, or to contact Microsoft asking for a patch to the OS...
Check for more information by the developer of Calligrapher...
Hoping this helps.
