Yes, that is possible. In the next release 1.7.9 (due out in a couple hours) you can use the following code inside a VBScript module.
timestamp = GetVariable("MOUSE_CLICK_TIME")
if timestamp <> 0 then
last = GetVariable("LAST_CLICK")
if last <> 0 then
write "Time Difference: " & timestamp - last
SetVariable "LAST_CLICK", timestamp
or see the robo-file below. Note that these variables are set when a user clicks on the main RoboRealm image. The timing is in seconds. You also have the variables MOUSE_CLICK_X and MOUSE_CLICK_Y which represent the location that the user clicked on. Watch the Watch_Variables module to see how these are set/removed on user interaction.
