I've been happily running perl programs on my Windows 7 PC for almost a year, and now suddenly they won't run without UAC intervention. When I give permission, they run in a new window, blink their output and close -- no chance to see anything.
I switched off auto updates some months ago (because they are too frequent, massive, and most importantly I was forever hitting new problems; and it seems ALL Windows updates are "important"(?), though very rarely actually apply to features which I use).
Anyway, the only software which I recently installed - knowingly - is for my Nokia phone. I've now uninstalled that software, and cold started, but the problem persists. (Apart from that, I have recently had problems with my Trend Micro Internet Security Pro slowing down the system, but Trend fixed that.)
I tried a "repair" installation of perl, but the problem persists. Anybody experienced same or similar, or have a clue about how to fix this?
