Description:
When in a SynMemo you pull the track-thumb to topmost (vert. scrollbar) or leftmost (hor. scrollbar), then the SynMemo scrolls to resp. eond of file or past eol.
Steps to reproduce:
See SourceEditor of Lazarus.
Open a sourcefile.
Place cursor at begin of file.
Grab scroll-thumb on horizontal scrollbar and move it to the left: text disappears, gutter is still there as are code-folding indicators.
Grab scroll-thumb oon vertical scrollbar and move to top: last lines of the file will appear.
This issue does not occur when you click the arrows of the scrollbar.
It looks like we assing some negative value to the scrolling mechanism when it should be zero?
Additional information:
The described behaviour does not happen to a TMemo, so it seems SynEdit related.
