I know exactly what you are suffering from, and the cures for some
1) PCK files hold the .exe and not any media. I find this annoying and pointless too.
2) *.* Wildcards do not work because of shortfalls in the editor - but if you download the latest editor (1.09b) it does actually work, sadly i'm not sure of the link and it doesn't appear to be on the patch download page - and I think it should be...
3) 2D media seems to be unreliable, I only encounter this when I finish a project and i've only finished about 6 since I got DBPro - i've not really 'investigated' this issue. I will say that i've had no trouble with 3D media and textures associated with them, I suspect this is a complilation error.
4) Included media in DBPro is in no way secure from even a fairly novice user and bloats the size of your exe by more than the size of your media.
As this subject has been raised a few times recently I think I will write a few functions for rapid loading and saving of encrypted media. I'll do it as DBPro functions for two reasons, firstly so you can change the encryption algorythm for extra security (although i'll use a password system anyway so novices can still be secure) and secondly because I don't have the tools or skill to make a DLL!
I'll do this over the next few days.
