Strange thing. I just was going mad the last 1 1/2 hour trying to find out why in the hell my project didn't want to compile with included media (having this < 1KB image inside). When I removed the inclusion of this file it worked.
I also tried to reproduce this behaviour under different circumstances and it happened everytime.
Everything is set up a correctly on my machine, latest drivers and both versions of DBPro (4.1 / 5.1).
What OS are you using? (maybe is this an os specific problem? can't imagine that, but who know?)
I'll give it a closer look ... u said you're running the latest? (5.1)
