I can confirm this behavior on RhoElements V2 and V4. I've tried many things such as
I can confirm that using energize.js and
$.mobile.buttonMarkup.hoverDelay = 0;
helps in RhoElements V2. I still need to verify this on RhoElements V4.
Any feedback from people that have solved this issue is appreciated.
Don't know if this is your issue or not but sounds like one I had.
There was an issue with Rho that a screen tap was seen as a scroll. This can occur if you move you finger a little bit when pushing the button or if you have large fingers. This issue was
addressed in Rho4.x and patch was available for Rho2.2 but would suggest going to Rho 4.0.
