Thanks for looking into this Zubaz,
I had CursorFX 2.10 installed and initially I had used Impulse, but then when it went away I uninstalled, did a registry clean and installed the stand-alone version.
As stated before I now uninstalled and reinstalled via SDC after a registry clean and reboot, but it still says version 2.10 when I click About, it still shows version 2.10 in SDC, and it still shows version 2.10.023 at the store for me as available. It does show on my list of installed software in SDC.
I am on Windows 7 64-bit. I did not check my XP or Vista as I really don't use them any more, but I don;t think that would make a difference.
