#17 Screen updating . . .

[Michael C]

One more little problem . . .

Windows XP SP1
MTT 1.2 Build 005

After loading a long list of mp3's (~4000) I noticed a
scrolling problem. If one attempts to scroll the
window with the arrow buttons on the scroll bar, there
appears to be extra horizontal lines in the same colour
as the lines that seperate each entry,

If I scroll by draggin the scroll bar, mouse wheel, or
arrow keys, the screen updates properly

The number of mp3s u can load depends on the available
memory u have, so u may see performance degradation with
very large number of mp3s loaded, but i plan to address this
in MTTv1.3 by using a virtual list view by which u can load
any number of mp3s (DWORD number of mp3s) without any
problems.. John G.

My machine is a P4 2.53, /w 1GB PC2700. I don't think that
available memory is the problem here.

I got the same in Win98 SE that was [eventually] fixed by
installing a newer video driver. Netscape is really good
for finding buggy video drivers :-(

May be related?

Filip,
this is a know issue of the list control used in VC++6, when
large number of items are loaded(even if u have 1GB
memory), it will be solved once a virtual list control is
implemented in MTTv1.3.. John G.

Another user using XP noticed a similar problem, it seems
the problem is due to the new XP common control, from build
005 onwards MTT included a standard directive to use XP
common controls (XP theme support added in 005) so its
probably the XP List control thats giving the problem with
large number of items,
try this file without the directive too see if it solves the
problem
