Launch registry editor and open the registry key /HKEY_CURRENT_USER/Software/ReenSoft/PIEPlus. Then tap [Edit] menu -> [New DWORD Value]. Enter Interval for the value name, 1000 to the value data, set the base to decimal as the default. Then tap [OK] button.
Soft-reset your device.
Now PIEPlus checks the launch of PIE every 1000ms. It may not optimize the first page when PIE launches. But other pages will be optimized well after the first page. If this works well, you can reduce the interval as small as possible.
Split text of <PRE> tag. This option is avaliable only on PPC 2000/2002. On WM 2003, PIE makes it to fit to page automatically without PIEPlus. The <PRE> tag may be used for showing the pre-formatted text like javascript code. Tap here to see the example.
