in reply to Tie::Win32MemMap and Tk

This cannot work (at least not without modification). Tk has its own event loop (MainLoop), and Tie::Win32MemMap(or Win32::MemMap) has its own (or it has a polling mechanism .... the docs have details). If you want this to work, you have to get them to cooperate.

update: see Give me my gui back! (specifically Re: Why not replace MainLoop?) for help on that (cooperation).

I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).
