Thanks sri, for pointing to a (near) excellent piece of software!
However, on my installation explorer.exe crashes the moment I resize any of the on-screen fences. Also, changing the ordering of icons in a fence of two 'columns' wide with 5 'rows' goes...how shall I say it: unexpectedly?
Besides these points (for me) this is software that should have been part of the Windows system (years ago, actually...).
