I created PDF from COREL X3. Acrobat 7 opens it OK, also placing in Indesign CS2, but shadows are distorted in Acrobat 8 and indesign CS3. All updates applied.
Can somebody try it?

PDF problem

I don't think there is a Corel issue, because PDF works in CS2 suite. Corel PDF creates drop shadow as a rectangle with pattern fill. CS2 suite places this fill in correct position, but CS3 shifts it.
I can't make 1.3 PDF file, because COREL makes catastrophic flattening. (it rasteries everything behind the bounding box of transparent object, but Indesign makes it perfectly). Finally I need 1.3 PDF, for Apogee RIP. The results are much better if the 1.3 PDF is made from Indesign. It went allways OK with CS2 suite.
Links are now OK. Sorry.

...this is what a postcript ends up doing anyway, any vector elements below transparency will get rendered to pixels, the same is true for indesign or quark to postcript or exported to 1.3 pdf...
...this also explaind the golden rule of keeping vector on top layers as much as possible, particularly body text...
...as mentioned above the issue is really with corels implementation with CS3, you could also argue that it is adobes fault, but clearly corel will likely have to create a fix as it is the source code acrobat 8 is trying to read...
...in acrobat 7 they all look fine apart from the CS3 created PDF...
...i'm not a corel user but in my experience the interaction it has with CS3 is bugged, as you are experiencing now...
...also, looking at your pdf files, the corel pdf is clearly RGB color, from indesign you are converting to cmyk via convert to destination profile i assume (whatever that cmyk profile may be), so you might want to be careful about what destination cmyk you are using here...
...we also use apogee 3.5 (though not for long as heidelberg have been around to measure up for better workflow), apogee is a great tool and well streamlined, just our plate processor is a thorn in the side and we've had nothing but trouble with the agfa upgrade policy, so the boss has had enough...
...had a similar job a few weeks back using corel x3, with gradients and the lens effect tool, nothing but headaches. Symptoms were as you have posted (apart from the hefty gradient banding we experienced), drove us nuts...
...we ended up (after much head scratching) exporting to 1.3 from corel, all color conversion to cmyk in the pdf export from corel (as lens effects are always RGB it appears), we avoided the import to any other program...
...we also ensured all other imported graphics were cmyk, along with text...

That's correct, but Indesign makes flattenig much much better than Corel.

I allways make color conversion in Indesign, that's the way I'm used to it, because i have different color settings for different machines (offset, flexo...). Usually export Corel files in native format, sometimes also in RGB, so all the conversions are made in indd - usually, when text is placed over PDF in INDD.

That was the solution with indesign CS2. Exporting PDF v6 without compression, in native format. All the excellent work with flattening, converting to CMYK was indd's job. Allways perfect. Now, with CS3... Looks, I'll have to have one dedicated machine only for CS2...

In Corel X3 all effects can be defined as CMYK.
...out of interest, does the corel 1.6 pdf you have rip in apogee as you see it in acrobat 8 (all shadows shifted)??
Unfortunatelly I have Agfa PDF Rip v2.0 series 2 - machine is Avantra 30 - CTF. It doesn't support PDF files with transpareny. But on the other hand, Colorproof XF works with "Source" file without any problems.
I still believe it's Adobe's bug.

...yep, adobe have changed the rendering engine in acrobat 8, though i can imagine that corel will likely end up having to make the fix so their pdf implementation becomes compatible with that new rendering engine...
...as i'm not a corel user, can it export to acrobat 8?
...if the corel pdf 1.6, RGB color is then into indesign for conversion and flattening, how do you deal with your black text?
...when you say catastrophic flattening from corel, have you tried breaking apart the shadow from the object (control + K) to prevent pixelation?
...also i've heard that trying to merge all shadows and lenses, wherever possible, into one flat image with the background can make things a lot easier to deal with from an output point of view...
