I have found in toradexcommon.reg the lines
; Fix left click problem on IE
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Gesture]
"GestureCapabilities"=dword:00000000
This disables gestures in internet explorer. I think this is not necessary. In order to get left click working I added to registry
[HKEY_LOCAL_MACHINE\SYSTEM\GWE\UserInput]
" PromoteMouseInputToTouchInput"=dword:1
Has this ever been tried at Toradex ?
