The solution I ended up with was to modify RowSource to reflect the current directory, after interactively changing the directory.

This solution never answered the problem of why an interative change (e.g. clicking on item) retained the directory, whereas a programmatic change caused a reset to the directory specified by RowSource on the next interactive change.

The directory contains a number of images the user may want to browse to select from, the currently selected image is displayed next to the list box. I thought it might be a nice idea to have an automatic browse facility, rather than require manually moving through the list, hence the 'autoscroll' using the timer.

Thanks for replying, if you've any idea why I'm getting the problem, I'd still be interested - I'd prefer to correctly fix the problem than have to work around it.
