I'm looking for the drivers that they talk about here:
How do I use the programmable hotpad?
The use of the programmable hotpads is explained in the Technical Reference Guides (TRGs) for each pen tablet. To use the programmable hotpad, you will also need the Hotpad DLL for the pen tablet. The Hotpad DLL can be downloaded from this Web site, either by itself or as part of the Developer's Disk for the pen tablet.
I've put calls into Fujitsu, but haven't had much luck. The DLL is nowhere to be seen on their site.
