This is just a cosmetic request and not causing me any problems.
My Laptop has a touch screen, but I rarely use it as a laptop. Instead I have two monitors hooked up to it and use them. However, with the touchscreen and Windows touch pack installed for Windows 7, the show desktop button on my taskbar has been made bigger to facilitate with the touchscreen usage and I like this. On the Display fusion taskbar, the show desktop button is the standard size, therefore they look different on my monitors.
My request is for a option for or an ability of the software to detect the windows touchscreen settings and adjust appropriately.
Hopefully to make it a little easier,
From my quick research you should be able to detect if touchscreen is enabled by the Software\Microsoft\Wisp\Touch Registry Keys, specifically TouchGate (1 enabled, 0 disabled). This can be found in both the HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER.
