If a directory contains a long file name (wider than the file list) the h-scroller moves automatically half a second after the mouse passes over the file list area. a/ this is a bug , only explicit user action of the scroller should do this. b/ in this case the filelist is unusable since shorter files names get scrolled out of sight and there is no way to view them once the mouse enters the filelist area. eg. Jazz manouche 00 Paco de Lucia & Al DiMeola - Mediterranean Sundance Rio Ancho-128k
Do you use single-click navigation?
yes that seems to be a key to producing this bug. I have just tried with double-click selection and the scroller does not jump, either on mouseover of on item selection. looks like you've found it.
Moving to 0.3.2final.
Can't reproduce this anymore, hence closing this bugreport. Please reopen if you can actually reproduce this issue.
