Remembering previously used folder.

that's odd!

Try this then.. here (v1.34) it works fine..

app=CreateWindow("dirtest",32,32,128,128)
button=CreateButton("RequestFile",16,8,96,24,app)
Repeat
	WaitEvent()
	If EventID()=$803 quit=True
	If EventID()=$401
		file$=RequestFile("load..")
		path$=cutfilename(file$)
		DebugLog path$
		ChangeDir path$
	EndIf
Until quit
End

Function cutfilename$(file$)
	For t=Len(file$) To 0 Step -1
		If Mid$(file$,t,1)="" Exit
	Next
	Return Left$(file$,t)
End Function

by the way :)

For t=Len(file$) To 0 Step -1

should it go down to 0 or 1 ?
