Right-Click on HP-Compaq L2105tm (TOUCHSCREEN) under Win 7 (32 bit)

I am running MS FS 2004 with 4 touchscreen monitors of which 2 are the new HP L2105tm monitors (with native Win 7 drivers) and the other 2 are AOC touchscreens (wth AMS Touchkit drivers) based on the older 5-wire resistive technology. In order to enable right-click via single-touch on the touch-screens, I use a floating toolbar swap-mouse-button utility (it interchanges left- and right-clicks when you enable it). This utility works perfectly under Win 7, in that the AOC touchscreens respond to single-touch with a right-click when the mouse buttons are so swapped with the utility. The HP L2105tm touchscreens however, will not. Under single-touch they will ONLY respond with a left-click, even when the mouse buttons are swapped.To double check, I clicked within the monitor desktop area using the physical mouse, and I was able to swap button clicks normally. But touch functionality is restricted to left-click only. Has anyone else faced this problem, and is there any solution?It could be a Win 7 issue as the AOC touchscreen monitors (which have their own drivers - these are not native Win 7 drivers) respond with right-click to single-touch under these conditions. Also the physical mouse responds to the swap-button program when clicked within the HP monitor. It has something to do with the HP monitor/Win 7 touch drivers itself. Please help!Multi-touch gestures (press and tap with second finger = right-click) as supported by Win 7 do indeed work normally on the HP touchscreen, but they are not easy to use within cockpit panels, so I do not want to use that route.I should add that I did try reloading the drivers, and updating them with the latest available, and also tried installing the NextWindow touchscreen drivers as offered by HP on their driver support for their Touschmart line, but the problem remains. It is indeed peculiar, because the physical mouse working within the "display environment" of the monitor responds to the swap-button utility. It is only that the "touch environment" of the monitor is not similarly responsive
