I got an unexpected "out of disk space" on my SC17 recently, and after a few minutes, realized the "problem" was the c:/users/public/pictures directory, which had a bazillion (plus or minus) BMP files, each 24mb in size.
Some of them dated back to January, then a few in feb, a few on Mar 10, then on march 16th, it basically started taking like 3-4 screenshots per minute, 24 hours a day, only missing those times it was in standby.
I rarely use the precisionX app, and have never (intentionally) used it's screen capture utility. Looking at the configuration, I see that the "hotkey" is blank. The field was empty. I tried setting it to a value (Alt-F1 or something), and even going as far as rebooting so everything has a clean start.
Nope. The minute I start PrecisionX (I disabled the "start when OS starts" when I discovered it was the culprit) - I start getting lots and lots and lots and lots of screen captures.
I admit, I honestly don't have a lot of value for the program - though I occasionally use the "underclock" option if I'm just doing work (telnet doesn't need a whole lot of CPU). But is this fixable? I don't see any updated versions or similar complaints, so maybe I just stumbled on some unusual config error.
