rainmeter-studio/Library/lua/LuaManager.cpp
Birunthan Mohanathas 4b30714520 - Fixed: Rainmeter crashes if the Lua GetStringValue() function returns an invalid value
- Fixed: Rainmeter crashes on initialization if Lua is invalid (e.g. syntax error)
- Fixed: Rainmeter crashes on mouse action if Lua file is not initialized
- Fixed: Measure=SCRIPT tries to process mouse actions even if corresponding function does not exist in the Lua file causing log to fill with 'nil value' warnings
- Mainly cosmetic changes to logging of erros in Measure=SCRIPT
