  • Resolution set to No Bug
  • Status changed from new to closed

When the mouse is moved (and the GUI is active) the $GUI_EVENT_MOUSEMOVE message is posted. Every time a message is received you update the GUI with GUICtrlSetData(). Since moving the mouse generates a lot of messages you end up calling GUICtrlSetData() a lot which burns up a lot of CPU cycles.

This is not a bug in AutoIt.
