OK not having a pronto means I am only posting what I believe to be the situation.... The best pronto .CCF resource I know is Remote Central
I would suggesting going there to search out any mouse controls but...
AFAIK the mouse emulation mode that the pronto supports (and I am keen to test... I rarely need a mouse now thanks to Girder, but my GUI's are mouse activated and so I am still with two remotes... If I can get this down to one I will pick up a pronto or wait till the Pronto Pro hits the streets) will only work with the Philips Rx unit that works with the Philips IR keyboard. Also these are no loger for sale !!! If you are quick
I noticed a post on the remote central forums page about a few of these being available either just the Rx or Keyboard + Rx...
Anything other than the coded in mouse support will likely be a little more flakey.
Please keep us informed as I personally am very interested in a new mouse input either Pronto mouse emulation, Gyropoint RF, Trackman RF or similar.
