Thanks Dave. Found it. Will definitely give it a try.

I ended up removing the plastic shroud on my Excalibur, allowing chips to fall through the table and out of the way...Then, I simply do the same thing that I've always done; vacuum everything after use...I'm not much of a fan of dust collection except when using my orbital sander...MOST other activities crate sawdust/chips that aren't near as much of an issue as compared to the dust that is created while sanding (and that sanding dust gets EVERYWHERE)...When looking at dust collection for scrollsaws, I see more disadvantages than advantages (my opinion/experience):
1. The design of the dust collection system inhibits the ability to perform "normal" functions of the tool (i.e. the shroud doesn't let the chips fall through, or as already mentioned, they get stuck in there).
2. Continually running a shop vac while cutting adds a lot of unwanted noise. The Excalibur is a relatively quite saw compared to my previous saw, and now that I've lowered the noise level to a real comfortable level, I don't want to turn around and raise it by adding a shop vac.
3. The blower (located above the work piece) is blowing dust away to provide a clear view of the blade/pattern, while on the the other hand, the dust collector (located below the work piece) is limited to what falls below. The point is that you'll need to vacuum afterwards anyway, regardless of how effective the dust collector is at capturing stuff below, because the dust collector (as designed) can't capture the dust created by the blower. On my Excalibur I have TWO blowers; the integrated one that came with the saw, and another one that I mounted on the side of the upper arm and connected to an aquarium pump. The integrated one blows from the side across the work piece, and the one that I installed blows back away from my face. As a result, I don't have any issues with dust around my face.
Back to the original question as to how it can be improved, here's my input...In order to allow the chips to naturally fall through the table, and not inhibit any normal function of the machine, the dust collection port should be located BELOW the travel path of the lower blade clamp (picture a wide shop vac attachment held upside down under the front of the machine). Use the same inverted vacuum attachment concept to catch the dust created by the blower by mounting a narrow channel/gutter all the way around the circumference of the edge of the table (some would say to simply replace the blower with a vacuum attachment, but I don't think it would be as effective at clearing the blade/pattern path as a blower; not to mention that it is easier to blow from above, and vacuum from below). This gutter doesn't need to be any wider than say one quarter inch, if that; it's only there to collect dust from the blower, not chips...Just some food for thought.
No Tony, It wont hurt the saw or the blade to stop the motor suddenly at the corner.
Sometimes you can just stop cutting at the corner and back the blade up back down the cut (with the motor running) and turn over to the other side of the corner or, you can stop the motor and do the same thing. Then after cutting out all of the center section out, go back in the opposite direction to clean up the corner to 90 degrees. (or what ever degrees is required)
Everyone has their own special way to skin this cat.
I don't think you can hurt a scroll saw short of throwing it on the floor or setting it on fire. The electrical problems are the only real worry and they can usually be repaired. Wearing it out from use or lack of mantaince are the real issues.
