This is a nasty bug: When I type a "x" somewhere into a new line of PHP code and wait a moment to get the Autocomplete window popping up, the compile button becomes disabled/inactive in the moment, when I remove the Autocomplete window again, e.g. by clicking with mouse into code, hitting Enter or ESC. To activate the button again, I have to open "Highlight Settings" once and close the window again. Apparently this happens only, when the PHP file is using the "HTML multihighligther". In this case, the button should be either always enabled, always disabled, or when hit a window should pop up giving instructions on what to do.
I will send you a short video via email clip documenting it. Btw: For "HTML multihighligther" the proper English spelling would be "HTML Multi-Highlighter". -- <https://forum.pspad.com/read.php?6,78195,78214> PSPad freeware editor https://www.pspad.com
