This week I tried to run DF6NM's OPDS (Opera Deep Search) program on 
my shack computer. The computer runs Win7 Ultimate which was an 
upgrade from the awful Vista. Markus's software did not run properly, 
producing a screen with various error messages and a corrupted list 
of callsigns. Having spent some time in conjuction with Markus trying 
to fix this, I finally came up with the following work-around.

I had discovered that the software worked well on my office computer 
that runs WinXP. So I installed 'Windows Virtual Machine' and 'XP 
Mode' on the Win7 computer (both programs free from Microsoft). I can 
now run both Win7 and XP on the same computer simultaneously. OPDS 
works under XP whilst Win7 runs the SDR front-end.

Hope this helps someone else run the excellent OPDS software on a 
Win7 computer.
