I went to the main site to investigate the Pro version..... it's just too dear for me to justify it.
The free version seems to do all I want except "thumbnails" view of images just give a generic Powerdesk pic for each one. Also I cant seem to change to "Save Settings Now" from "Save settings on Exit" in the Options menu. I presume these are limitations of the free version?
I can live with these however as I have a great utility that came free on a coverdisc some time ago that enables easy viewing in this way, "picaview".... as for saving the setting... well I'll get used to it!
I've had a few icon wobbles since installation as well, but the Icon repair feature in TweakUI seems to have sorted that.
Shame that Windows explorer wasn't behaving itself really!
Thanks again folk,
