Dear all
I found accidentally at least there is two RichMemo package in the net.
One is available at
https://github.com/skalogryz/richmemo
richmemo-master.zip, time stamped at 13:04 of 2022-07-27
another is at
https://sourceforge.net/projects/lazarus-ccr/files/RichMemo/RichMemo%201.0.0/
richmemo-1.0.zip in 2009(day and time vary)
Former is newer, does anybody know the difference between the two?
