Sandboxie 3.64 (x32)
I've lately started using a stylus and tablet and find that workflow's much better using X-mouse, which can foreground different windows for you and set the focus/caret to them just by the position of your mouse-pointer. This is useful glancing at references or with multiple monitors, different editor windows open to sample colors, etc.
Thus far I've just been using the X-Mouse option in TweakUI (v 188.8.131.52 for XPSP1 and higher... http://www.softpedia.com/get/Tweak/System-Tweak/TweakUI.shtml
) to enable this. It's nice given it just makes changes and can be closed (versus adding one more utility process that can crash at any time and break functionality until I restart), but it still gets rather tedious to tick off the checkbox to use the feature then "apply" changes each time I change to look at my inbox or something while I'm working.
I was looking to use Sandboxie to figure out just what settings are being altered so I could implement a standalone control and link it to shortcut, however I think registry-access is not being controlled correctly. Unsandboxed there's a change to UserPreferencesMask in HCKU\Control Panel\Desktop but when sandboxed SandBoxDiff reports it's done nothing (no writes) to the sandbox hive. In addition, there aren't signs that anything else was done, including whatever magic Tweak does to populate the registry changes to the operating system and have them become active. Finding /that/ out is really the key here. I feel like I might need still a finer-toothed comb.
