Sorry for the late reply.

The SlideShow uses that buggy CanvasLoadAbs command.

Here is a workaround for SlideShow that simply replaced CanvasLoadAbs with a user defined MyCanvasLoadAbs:-


1) In the card timer - replace CanvasLoadAbs(1,fname,1) with MyCanvasLoadAbs(1,fname,1)

2) In the MainCode section create a new procedure called MyCanvasLoadAbs, with parameters, cid, fname, scale

Code: [Select]

local fname1,fname2,fnameloc,f1,f2,fx

Put fname into fname1

@ Original
FolderItemGetAbs(fname1,f1,fx,fx,fx,fx,fx)

@ Local
Put 'temp.jpg' into fnameloc
Put MyFolderFN into fname2
Append '\' onto fname2
Append fnameloc onto fname2
Put fname2 into field 2
FolderItemGetAbs(fname2,f2,fx,fx,fx,fx,fx)

@ Copy to local
FolderItemCopy f1,f2

CanvasLoad(cid,fnameloc,scale)

FolderItemDelete(f2)
Basically it just copies the image to a temp file temp.jpg, loads it inot the canvas, then deletes the temp file.
