rainmeter-studio/Library/System.cpp
spx 64888434c9 - Added !RainmeterWriteKeyValue. (based on MattKing's code)
!RainmeterWriteKeyValue "Section" "Key" "Value" ("FileSpec"), where "FileSpec" is an optional parameter. If FileSpec is not present, the change is automatically done in the currently running skin file. If the bang is executed from command line, FileSpec is required.

- Some improvements of MouseOver/Leave detection.

- Fixed the issue that window dragging brings on MouseLeave if "Show window contents while dragging" is not set.
- Fixed the issue that window dragging can't be begun by dragging the Button.
- Fixed the issue that a reaction of the upper Button penetrates to the lower Buttons or the other window.
